I keep hearing how people are able to concentrate, focus, pep in their step... from using this medication for ADHD but I've had a COMPLETELY different experience.

I'm exhausted all the time, lost motivation to do anything, gained 10 pounds in 2 months, take 3 hour naps in the afternoon and have trouble remembering the simplest things like words when I'm talking to someone. I literally sit all day doing nothing. No desire to go out with friends on the weekend. Don't care that my kitchen is full of dirty dishes. My procrastination is way worse. I've just seem to have lost interest in everything for some reason. I can't even seem to look descent for work anymore. I look awful and feel tired. Why?

I'm currently taking 20mg in the AM and 10mg in PM for almost 2 months. I do take "breaks" but that makes no difference at all. Is my dosage too low? Too high? I hate to give up so quickly on what should be helping me, but actually making me worse.
