For me it's less sleep, and wanting to do reckless, potentially dangerous or damaging things. Also agitation and feeling like i'm not doing enough with my life, or my life is too serious and not wild enough. As things progress i want to start taking drugs, and i start having spiritual thoughts that travel down a path to some pretty crazy thinking. Whenever I'm not well i get stuck in the same kind of spiritual thinking, which is probably delusional, but part of me still thinks maybe it's true, and i just can't connect with it or see it in my normal state of mind.
