I recently got diagnosed (around a month ago), and was put on Concerta at first. But then I always felt sleepy a few minutes after taking it and I feel like my impulsivity is still there, and my brain is still "lagging" at times, so my doctor switched me to Ritalin last week (Methylphenidate is our only option in PH). I feel like it does a better job at keeping me awake and I feel like I don't have that "brain fog" during clinical duty. But! This is the first day that I took it when I have a lot to do and don't have duty, and I'm struggling a lot when it comes to pushing myself to actually start doing things.

Other people are extremely focused after taking Ritalin, and some get hyper, but I feel like I don't have that significant "focused" moment. Do I just have to get through the hard part of having to start? Also, do you also feel extremely sleepy hours after taking stimulants? What am I supposed to feel? What are your experiences on stimulants?
