"i have add, anxiety and depression. i began 100mg once a day for a week then went to 100mg twice a day. you have to give this medicine time to work. the first i was thinking of not taking it anymore because it made me feel so tired. but i&#039;m so happy i stuck it out! my overall mood, attitude and outlook has improved tremendously. my mood and attention is consistent, unlike when i took adderall and would experience crashes. this medication has made a world of difference. i&#039;m less anxious and happier."
