ADHD
"I was diagnosed with ADHD when i was about 5 and my experience over all has been amazing ive been on it for 12 years now i take 40mg once in the morning and in the afternoon and by like 6pm it wears off(btw im 6 feet tall and weigh 225 lb thanks to this medication).  The only bad parts or symptoms im having are that Caffeine has no effect on me anymore( probably built up a tolerance thanks to the focalin) , I dont always sleep to well, and ever since i tuned like 14 my appetite went from non-existent to out of control (dont know why...) im 17 now and am an A- Student where as i was an F student before, I definitely recommend this but i should warn you all its not for everyone there are alternatives."
