Have you ever been tired for so long that you just become no longer tired? Like your body is just like "oh okay we can't sleep yet, keep going buddy." I sometimes get VIOLENTLY tired, usually at work, and then buy the time I get home it's too late... I'm not tired anymore. I might actually have a sleeping disorder or something.
@dcc @charlie_root yeah that's my other problem, I have a mood disorder and it fucks up my sleep when I get hypo mania and literally can't sleep. But this happens to me anyway, even when I do have a good string of consistency :P I just kind of have to accept my brain is fucked lol
