dude you basically are going through puberty again... and your body is in a constant state of growth, you grow the most when you sleep,, hence the always sleeping, whenever im on high doses of shit and growing alot, im lucky if i can makeit to the gym 4times a week im just so dam tired, but thats good shows your growing and its working, just make sure your going to the gym... caffine ephedrine might help a little... it should pass in a few weeks..
