You haven't mentioned your dx and what meds you're on, if any.
I would advise against self-medicating with uppers and downers, especially if you're on any psych meds.
I speak from experience. Before my dx, I self-medicated with alcohol for 30 years. Alcohol is a downer. I used to it sleep, I used it to cope with social situations, with a bad marriage, with work problems, and so on and so on. I never was addicted, and very luckily, I am not an alcoholic, but I probably delayed my diagnosis and the chance of getting any real help by 40 years.
Self medicating is never good.
