adhd
"I started using this medicine when I was 24 (three years ago), after I was diagnosed with ADD. Up to that time I had been struggling with school and getting work done. I have always been able to compensate because of my intelligence. Writing essays was a pain, because I could never sit down and focus. 

I feel that this is a two-edged sword. I felt I was finally able to concentrate on my written work. It works wonders on that respect. But I also feel that the side-effects can be bad, I felt anxious and my heart often started racing. Regular use can reduce this, but I feel bad about relying on meds to lead a normal life. It helps me when I have to do concentrated work, but otherwise I don't take it."
