Welcome Michel,

I have only played a bit with gags myself, but I too get that reaction of feeling like I want to wretch. Last time I tried, I swallowed each time I felt the gag reflex coming and that seemed to help. Whether it was a mental thing of the swallowing taking my mind off my reaction or if swallowing actually did it, I am not sure. I then managed to be able to keep the gag in for a lot longer. I have one with a breathing hole in a well, and it does seem to help also.

Hopes this helps, would love to know if it makes any difference for you.
