Got tested for AD(H)D and was found to have ADD.. got obscured by the ASD that I also have for a long time, but it has become clear that the ADD is there and always was.
Had fine experiences with methylphenidate in the past, but that was just on occasion, sometimes functional sometimes recreational. I already knew that abusing it kind of sucked by comparison. Then when I tried it medicinally for ADD it was too harsh for me just like abusing it was, I get more insomnia, anxiety, physical issues etc. Here in the Netherlands the second option is dexamph... pretty sure there isn't any Adderall here and I think dex is more effective anyway and don't see why anyone would opt for Adderall. different reactions in other people I guess.
But yeah usually I avoid mixing something like amps with even weed like the plague. Mixing too much amps, weed, 3-MeO-PCP type stuff as well, g perhaps, can easily lead to trouble because they amplify each other's tendency to go nuts. So LSD and amphetamines shares those same risks which is why I kept my doses relatively low, which is doable. I definitely wouldn't recommend just taking recreational doses of amps with it or more acid.
