I'd say the my main "addiction" is caffeine . When I'm depressed I just have no energy so I overload on it. Same thing when I'm hypomanic, I get the urge to make me feel even more wired because I feel I can do even more (that's bad I know...). I used to do cannabis a lot as well, as an escape too. For a sleep aid, it knocked me out for way too long. What made me stop was a terrible night having eaten way too much of an edible and not only getting physically sick but succumbing to extreme paranoia. Honestly it was one of the scariest nights of my life, not only did I begin to hear voices when I never had before, but I awoke covered in my own vomit. I just never want to go through that again, though knowing myself I will get the urge once more eventually...
