man..I've been wandering why I've had such bad cramps since I've been on clen. I figured it was the clen. but never really gave it much thought. I've been eating shitloads of potassium and drinking a ton of water and I still get cramps.........I can hardly do any cardio. Good thing I just finished that shit....now I don't have to worry about the cramps any more. Who says you don't learn something new every day!!!!
