This is how I feel too. They have me on 108 mg. The main thing with concerta that bothers me the most is the loss of appetite. I literally can't stand food when I take concerta, it's like I can't even taste anything at all, but my mind feels so free. It's an amazing feeling when you can actually think about things and take them in instead of losing it as soon as you hear it. When I take it I'm very attentive, but very antisocial as well. I don't know why but it's just like you don't want to be bothered. It makes me feel even more depressed and sad than I am reguraly am as well. I don't know if this will help at all, but Last year I was tired of how it made me feel so I started taking less and less until I didn't take any at all. A few months later I decided to take my medicine again for a day because I had a very important test to take at school. Bad idea. It made me very.. I don't know how to explain it, I guess it was a kind of high. I did well on the test and everything but I was completely out of it :\ it took me a fair amount of time to understand what people were saying to me; for me to take in what they were saying. I remember sitting in one of my classes, and I was freezing cold. I put my hand on my friends face beside me (yes I know this was weird x) and he noticed it, too, even though it was a very hot day. This lasted for another thirty minutes or so then I was feeling back to my self.
Sorry for the lengthy post and if it's sortta scattered I'm very tired haha
