Causing weird problems for me

Hello all,

I have the progasm model and a day ago I had a long session ~5 hours. Last night as I was trying to sleep I could feel my muscles clenching and twitching, i wrote it off as a nice pleasurable feeling. This morning I work up by a forceful jerk in my leg not pleasurable just a spasm and all day I have been feeling the twitching muscles, from my anus to my calf, all the way to my biceps.

While the session was nice I fear that this sort of reaction hinders my ability to live my actual life. Has anyone had this problem, if so how long did it last and is there a way to stop it quickly. I have no intention of using the aneros again until this sensation stops. Its like I just had 15 cups of coffee and I feel like I need to stretch but its never satisfied.
