"i&#039;m 32 and have been on this drug for about 8 months now. for me, it&#039;s been incredible. i am no longer on an emotional roller coaster and definitely more patient and no where as near irritable as i used to be. i&#039;m on a dosage of 120 mg daily. i take it at night before i sleep. however, a possible side effect for me is hypothyroidism - but, i did have hyperthyroidism as a child so i don&#039;t know if strattera caused it to come back as hypo or it&#039;s because of my age. i did unfortunately gain considerable weight, but with the thyroid pills, i have been slowly losing it again."
