I pretty much have no clue what you are talking about
I have no idea if its related, but after a really heavy training day (or contest) I usually wont sleep that night. I know some powerlifters with the same problem. Dont know the cause.
also, limit the stims.. its just a matter of time before you actually need them pre-training. Ive been there. now its 100mg caffeine max (ie a big cup of coffee).
