I tried Ritalin (officially prescribed). buth that made me very unstable.
I tried dextroamphetamine (officially prescribed), but that may me rather numb.
I tried various illegal substances including LSD, levoamphetamine, methylone and 2-FMA (self-medicated). Those did benefit me a lot, but the stimulants to tend to be addictive and result in dependence.
Currently, I try to stay free from any medication most of the time, although I do self-medicate occasionally.
