Tomorrow and Carpel Tunnel

So tomorrow I am having carpel surgery on my left hand. I had it on my right hand a few years ago and it really helped me. However the procedure was a bit stressful. I had a student observing the doctor so he was explaining it to them. Well next thing I know I feel my hand mysteriously lift up on it's own. I was relaxed on something but was awake and my hand was numb. Oh it totally creeped me out. I am praying that this doesn't happen and maybe they could give me something heavier... We will see.
