adhd
"I was on Ritalin/Concerta since I was diagnosed with ADHD at the age of 6 (I am now 18). I switched to Strattera last September, and that was horrible, didn't do a thing for my ADHD. 

I went back on Concerta, but noticed it wasn't working as well.

My psychiatrist switched me to Vyvanse 40mg in the morning, and I immediately noticed the benefits, 100% better than Concerta and 400000% better than Strattera. 

Only side effects is lack of appetite but I am welcoming that side effect because I also suffer from binge eating disorder.

It helps my concentration immensely (I suffer with severe ADHD, to the point it's hard to have a conversation without zoning out and not listening).

Vyvanse is a life saver!"
