Pyroluria, manifesting Schizophrenia, OCD, and OCPD when my Zinc count is low.
Insomnia, from further back than I can remember.
Algolagnia.
Ex-PTSD.
Blunted Affect, or something like it anyway. I only really feel fear and anger for emotions, and even those I've put in check with enough conditioning to desensitize them (anger makes me laugh compulsively and get sort of dizzy, not a fan).
Currently? Smoking seems to allow me to sleep once a day, but it can take forever for that sleepy window of opporitunity to come about. If I miss it, I'm back at square one.
Drinking makes it easy mode, but hangovers make it a bit much to try to keep up as an every day thing.
As I mentioned before, sleeping medicines just mess with my head instead of putting me to sleep (what ones I've tried anyway). I've tried exercising to the point of physical exhaustion, reading or watching boring things, forcing myself to go to bed when I'm not tired with no stimulus, ocean sounds/whale calls/nature sounds, so many things. Too much going on up there to rest when I'd like to, even when I'm tired as hell.
