Yes, thanks I should have been more clear that I knew that going in. It was the contrast that surprised me. I wasn't sure if the original hunger was just my excuse for over eating, or something I was imagining. But after talking with other people who don't take ADHD meds, I found they had the same hunger level as I do on the meds, but naturally.
Reduced appetite or appetite suppression is a very common side effect of those types of medications.
