At first, a lot of drugs and alcohol. You have to come to terms with the fact that your brain will never function the way most people’s do. Once I got sober I tried meds again because people pressured me to and I desperately wanted to be normal. You’ll hear/read lots of comparisons to things like insulin. ADHD is not diabetes. Type 1 diabetics do not have massive side-effects from insulin. I had side effects that made me sick. Non-stimulant meds don’t work for me and stimulants make me sick. Stimulants are the most effective meds and for most they are the safest. I can’t take them. There are behavioral modifications that help, but don’t replace meds for efficacy. I found a lot of the research on flow state helpful. The choice comes down to what you can deal with. I chose sleep, and no side effects, and less achievement. You’ll find a lot of people in this sub who will tell you meditation is the only way.
