You are on so many uppers that I would be surprised if it is meds very much. I know the klonopin makes you sleepy but sleepy enough to make you really tired over top of the stimulants? That seems unlikely to me. (Keep in mind that 2 mg of klonopin doesn't sedate me so I'm not completely unbiased here).

I'm guessing but with those meds that's going to stay my guess.
