Hi, I have been taking Ritalin (20 mg) not for ADD but for another health issue since January of 2015. From then on until around May of this year it was doing wonders for me. I was at the top of my class without really trying, I felt happy and confident, and I lost a significant amount of weight (Before I was slightly overweight as I had been my whole childhood, and after I was at a normal weight and was actually needing to eat more than usual just to maintain it). Since May, I have not felt like myself, I have gained about seven pounds and while that isn't alarming or anything I just feel bloated and have no self-confidence. It's more difficult to get things done and I feel completely antisocial, even amongst my closest friends. Granted, I am leaving for college in a few weeks, but I didn't feel any notable stress or anxiety when this all started so I don't believe that could be the driving factor. So, I'm wondering if Ritalin can eventually plateau, and if there is anything I can do to reverse this? Going off of it isn't really an option because the issue I have is not one that can be cured, only maintained.
