dude, the same thing has happened to me the last two times I got all tweaked out! And it really flipped me out! Everything was fine all the way through, until right before I started to come down. Then all of a sudden, my hands went numb, and then my upper thighs started to go numb. Needless to say that I started to freak out, because I've always heard that your limbs go numb when you are about to have a heart attack! But after about an hour of pacing around my house, smoking cigarettes, and calling my boss for moral support...I was fine. It was rough though... But I have to wonder, what causes this? I told my friends what had happened to me, and they looked at me like I was crazy. I was even told that maybe I shouldn't touch the crystal anymore...and unfortunately, I might have to agree with them...
