"on my 4th day of adderall xr! i just bumped up to 20mg today, and let me tell you, best adhd drug i have ever taken! one, i feel happy and content. two, i am a ton more focused! and three, i can sit on my couch and just chill or go out and play basketball with my friends or basically do whatever, my motivation is amazing! i tried focalin xr, concerta, strattera worked for a year, then just stopped working. but i asked my doctor to let me try this medicine, and that is the best choice i have ever made. no insomnia but be ready for a loss of appetite. i lost 8lbs. in the 4 days i&#039;ve been taking this. as long as it keeps working as it is, i can see me being on this for a long time."
