This has been driving me nuts for the past few nights. I've trying to go into SP but my body always gets really numb and eventually I just can't take it so I force myself to move. The thing that gets me is when I start feeling all numb it's impossible for me to realize if I'm entering SP(as in my body is going asleep or whatever), or if I'm cutting off circulation and my arm is going numb because of no blood circulation. This morning I tried it a couple again after waking up and each time my arm went completely numb I immediately opened my eyes thinking I'm just blocking the blood flow.

Is there any way to tell the difference at all? When I did actually move my arm again I'm thinking it actually did feel like when you usually are moving a body part after the bloods been blocked out for awhile, as in it was feeling tingly for a bit afterwards. But I'm not putting my arm in any position that's abnormal(in fact it's just laying flat on the matress). Another thing is that it was just the one arm while my other one wasn't going numb at all.

Any advice appreciated.
