"i&#039;m an 18 year old girl and i have add along with bipolar/schizoaffective. because i have psychotic symptoms, the highest dose of adderall i can take is 30mg. my problem is, it doesn&#039;t keep me focused more then 3 hours or so because the dose is low and even though it&#039;s a low dose, i can&#039;t seem to eat at all. i&#039;ve been struggling with my weight for a while due to hyperthyroidism. i&#039;m 5&#039;00 and 89-95 lbs. my goal weight is 100. i can&#039;t afford to lose more weight. the risks are outweighing the very minimal benefits."
