You guys are talking about Twitching, basically right lol?
Where your hand maybe doing nothing and one of your muscles just starts to Twitch?
(Aside from the possiblity that your tweaked out from Crack) just kiddin
lol, I'll check in my medical book I got when I get home, had the exact reasons listed in there if im not wrong. Muscle contractions bring Magnesium/Calcium/Potassium/Electrolytes into mind though. Anybody care to explain meanwhile and confirm wether this Twitching of muscles is due to a lack of a particular mineral or minerals?
