I'm not talking punishment in the wink wink sense where we give you a spanking for being a "naughty girl" either. I mean as an actual "you broke the rules and there are consequenses" punishment designed for a more or less full time sub.

The punishment - first, secure the punished, through any preferred method in your desired location. More than likely in the nude to take away as much sensation as possible from havin things rub against the skin if they shift. Though for this purpose, they should be as secured as possible to prevent movement at all. Now, I've seen sensory deprivation hoods but I don't know a great deal about them. I assume they do the rest of what I need. Which would be take away their sight, hearing, and sense of smell (noseplug of some kind). Breathing would have to be through the mouth. In other words depriving them of as much of their senses as possible.

Leave them, without any other stimulation at all, for the duration of the punishment, left in the dark (for almost all senses) and unable to move.

Two questions.

1- Is this a reasonable thing to assume could be an effective method of punishment? It's not supposed to be pleasant. Or even neutral. It's supposed to be uncomfortable, though much more in the mental sense than the physical. Even thinking about the experience, personally, for more than a few minutes makes me rather uncomfortable, but any other feedback is welcome and encouraged.

2- I have literally no idea about how long to do this for. I assume the lack of sense involved must effect the passage of time somewhat (meaning things might seem to take much longer than they really do). If I had someone with me, I'd be willing to test this on myself as an experiement under their supervision and assistance. Until then I'm required to rely on the words of others. What would an hour like this feel like? Two? Longer?

Anyone who has something to offer, please share.
