ADHD
"I am 21, I&#039;m studying in physics and I have been on adderall for almost 2 years now. I started at 15 mg and I am now at 25 mg. It was good the first year, very effective. But now, I don&#039;t think it really helps. I feel sleepy with it and I lost attention very quickly. I don&#039;t think the dose is the problem, I feel the effect and I think that increasing the dose will augment the anxiety cause by it (I noticed that each time I had to augment the doses, the side effects was worst). 

I&#039;m gonna return to Ritalin tonight, it was way more effective. Or maybe another one with methylphenidate. Concerta didn&#039;t works for me, maybe biphentin should."
