In my experience with mental health adventures, sleep is absolutely essential.<p>It's difficult to explain, but when my sleep patterns become sporadic or light, my behavior and thought processes become... erratic. The way I internally describe it is as "heady", where my mental state has an almost physical feel that almost matches the feeling of blood rushing to an arm or a leg after standing up. During this time, I can get extended periods of hypomania and isolation. The only fix I've found is to simply get an amount of sleep that makes sense, which makes me think that there's an enormous correlation between mental health and sleep.<p>Edit: For what it's worth, it's also the same feeling I get when I don't take lithium.
