"i took this for tics and adhd.  i went up to 3 mg a day and felt horrible. very tired and body aches. it helps somewhat with nervous tics but not that great and side effects were bad. i quit it after 1 week at 3mg. and i am 200 lb man and it still was too much for me. the 1 mg and 2 my doses didn&#039;t really do anything positive or negative."
