Not saying it can't be the methylphenidate, but I would suspect it likely has more to do with your career than you might be giving it credit for. I don't know what your background is but, since you're on HN, I can make an educated guess and say you work in tech, which can both be a highly rewarding career but also one that can really drain the soul. The worst part about the soul-sucking is that our jobs are superficially very comfortable, so it's easy to talk yourself into just appreciating what one has and ignore your feelings. I recommend giving up caffeine if you haven't done so. That alone had a much greater impact on my daily functioning than taking breaks from my medication. It took my body a week to recalibrate, but my mentality and my energy has been way more even throughout my days. The nice thing too is I can sometimes have caffeine when I feel like I can benefit from it and it actually has a positive effect rather than just keeping you barely at baseline for a few hours.
