Yes, and there's even a name for it.
On some sites, it's called "sub drop", on others "bottom drop".
Here's an article that provides a bit of insight into what many experience.
Sub Drop
by David Williams
Sub Drop is a term used to describe the after effects of a scene, both physical changes in the submissive's body and mental and emotional results of the scene on the submissives mind. While the physical effects usually occur shortly after the scene, the mental and emotional drop may take days to manifest and thus are often not thought of as a result of the scene.
It is important to note that sub drop is not a sign of a bad scene or lack of enjoyment. Sub drop actually most often occurs after a very intense scene where the submissive completely releases and finds sub space and a sense of euphoria. Thus, in fact, the better the scene, the better the chance for sub drop of either kind.
Aftercare and attention to small signs can help identify sub drop quickly. Simply noticing different behaviour patterns or actions can make dealing with it much easier when caught in earlier stages. This is another reason why knowing your play partner is important.
Physical Sub Drop
Physical sub drop comes from two sources, sometimes mixed together, in some people they suffer one but not the other. Both are the result of the strenuous ordeal of a scene on the submissives body. While it may seem they just stand there and take it, in fact there is much going on and much energy being spent during a scene on the submissives part.
The first form of physical sub drop is a lowering of body temperature in the extremities, stiffness, numbness, and an over all tingling sensation. This is caused by a centralization of the bodies blood supply. The body sees the scene as a form of trauma and one of the first defence mechanisms for this in the human anatomy is to suck the blood supply into the main torso to protect the vital organs and brain.
The result of this action by the body is decreased blood flow to the arms and legs. This often results in very cold limbs after a scene and lack of sensations. When a submissives limbs are inordinately cold after a scene or when they complain of tingling, numbness, lack of sensation, stiffness, aches, or muscle cramps, these are often from lack of blood flow. A vigorous rubbing of the limbs will help to restore blood flow quickly.
Often this will leave a submissive wobbly after a scene and unsure of their grasp on items. If a submissive feels this way after a scene then it is best to have them sit down, legs extended and arms at their side while you rub the limbs to restore control. Crossing the legs or folding the arms can impede the return of blood flow and should be avoided. Laying down flat is a better way for this but is hard to do at play parties and such.
When rubbing the arms and legs, apply gentle pressure and release as you rub, this helps open the passages up to allow a greater blood flow. Cramps can be dealt with by applying a point of pressure to the direct area cramping, pushing in very gently and then releasing. This causes a fast flow of blood to sweep away the built up acids causing the cramp.
Understand that these physical manifestations are completely natural and not a weakness on the submissives part. Stretching out before a scene or after can also help lessen these effects somewhat but don't push too hard, a submissive can actually damage themselves by doing too much when their limbs lack full sensation. The basics work best, better to do small repetitive stretches rather then one big one.
Important Note: If the submissive is not in shape and used to stretching, do not expect her/him to suddenly be doing intense stretching before or after a scene. Stretching can tear muscles and stress tendons very easily.
The second form physical drop can take is the result of substances and chemicals in your body; namely, sugar, adrenaline, and endorphins. These naturally occurring substances interplay with one another to bring a gambit of results much akin to the after effects of a strenuous workout.
Eating a light high protein, low carbohydrate meal an hour or so before the scene can help alleviate a lot of symptoms, just make sure to have enough digestive time before you play and make sure not to over eat and be stuffed Lots of vegetables will also add nutrients that can help the submissive recover from a strenuous scene and of course, plenty of water before and after the scene will help as well.
When a submissive is scened often their body uses a great amount of energy. After the scene is over they will feel an intense craving for sweets. This is not bad, this is their body craving sugar to replace the energy lost during the scene. Sometimes this craving is accompanied by a shaky feeling. Sugar crashes can also bring about mood swings, grumpiness, irritability, and sadness in some cases.
The best rule of thumb to follow with this is: The simpler the sugar, the faster the results. Fructose, sugar found naturally in fruits, is easy for the body to metabolize and use fast. Apple juice, grape juice, any sort of natural fruit juice will help to restore the blood sugar level fast. Soda and processed sugar take longer to produce the same results but will eventually get the job done.
Adrenaline is often released during moments of pain and stress. It creates a feeling of energy and strength, often allowing a submissive to take more in a scene or to play longer then normal. When the adrenaline rush is over though, often it will bring about a feeling of weakness, shakes, and irritability.
Adrenaline is sort of like an octane booster in our bodies. It boosts the octane there already and causes the body to burn through the sugar in the system faster. Usually adrenaline crashes and sugar crashes occur together, once the body is no longer in overdrive, it has burned up a lot of energy and needs to replace it, fast.
Endorphins are released during periods of heavy muscular exertion or pain. Not surprisingly, they are often released during a good scene and tend to bring a very euphoric feeling to the submissive. When the effect passes though, the feeling of euphoria can crash into a feeling of melancholy. Imagine feeling no pain and just as blissful as can be and suddenly that is gone. You don't feel bad, but you don't feel as good any more either. By itself this crash will not often affect the submissive much but, in conjunction with the sugar and adrenaline crashes, it can enhance their results.
It should also be noted that replacing lost hydration (drinking a lot of water), replacing salts (drinking Gatorade) can also help with these things as well. Muscular cramps can be caused also by a loss of potassium in the system during play, eating a banana or drinking Gatorade will help restore this quickly. Think of the physical aftercare like that of an athlete after a tough competition. The submissives body will often crave the same care and refuelling as an athlete's would after a great exertion of effort.
After a scene and aftercare, it is common for submissives to feel hungry. Eating nothing but junk food can cause a very tired and weighty feeling. Remember, the body has used a lot of nutrients in the scene and needs those replaced. Proteins (meats, cheeses, nuts) will help the body recover but may be too heavy for immediately after a scene.
There is nothing wrong with craving sugary treats after a scene as long as you balance it out with a good meal as well later on. The results of eating only junk food can be a very bloated feeling later that night or the next day which can trigger aspects of mental sub drop (feeling unattractive, bloated, depressed). Eating a good light meal of proteins and lots of veggies will replenish the body of the nutrients lost during a scene. It is advisable to do this when the submissive has recovered sufficiently from the scene later that same day.
If the submissive does eat treats directly after, balance that with intake of water to help flush the system as well to avoid a tired feeling. Fresh fruit is always a good thing to have on hand after a scene as it can satisfy the sweet craving, provide simple sugars, and will not leave the system bogged down with junk food.
