Most bipolar people shouldn't be treated for ADHD with stimulants. It's a very thin line that if crossed could cause the patient some serious issues. It's not very easy for a lot of pdocs to want to try to stay on that line.
I've tried other stimulants too.
Methedrine. I think this is the pharmaceuticals equivalent of meth. It was ok briefly. I didn't like meth for more than a few minutes either.
Coke was just enough that I was ready for bed. No joke. 3 people split 8 ball. I went to bed.
MDMA was never as strong as everyone seemed to think. I found it too expensive for that feeling. I found other ways to get the same effect temporarily and much cheaper and legal. No, I won't tell you.
