"i was 20 when i started staking strattera. as far as focusing yes, i was completely focused and motivated all day! if i was sitting still i would have to pull out my phone and play a game to keep my mind moving. however the side effects were absolutely terrible! i was constantly sweating and if i wasn&#039;t sweating i had chills! i began suffering from insomnia. i have constant dry mouth and headaches. the worst side effect by far was what it did to my menstrual cycle. it gave me a extremely heavy and very crampy cycle. it also made my very regular cycle completely irregular. the side effects made it not worth it at all."
