adhd
"I've been on 18 mg concerta for 3 days. I'm a 39 year old woman with ADHD-PI with anxiety. 
The 1st day I felt fluey and extremely tired, but very mellow and happy, nevertheless it didn't do a thing for focus/Attention. The 2nd day I felt inconsistent fluctuations with my mental clarity/focus. Also, there were fluctuations in Tiredness, I had to drink caffeine twice in the day on order to kind of function. Also my appetite became enormous. I still felt quite calm and centered though, which was nice for a change. 3rd day was more of the same from the 2nd day, but my appetite was less. I'm wondering if I should keep taking this."
