I have ADD and BP. Actually, Adderall is what gave away that I have BP. My pdoc and I thought I only had ADD and she prescribed a small dose of Adderall for me; I think 10 mgs or so. Even at that small a dose, it threw me into the worst mania/mixed state I have ever lived through.
At first, I was so euphoric! I thought I had found my wonder drug! I was running around doing all kinds of stuff, laughing at everything, dancing like a maniac to music I don't even like. Every thing was so much more vibrant. Colors, smells, food (when I ate, which was not much because it completely took away my appetite). I just thought that this was what it was like to be happy for the first time in my life. How deceived I was.
Then came the psychosis. I thought I was possessed by a demon. I had some visual hallucinations. As you can imagine, things just got worse from there. I went into a mixed state, which is absolute non-stop torture. It lasted about 3 months. I had to quit my job. My pdoc tried to stabilize me with new meds, but nothing worked and eventually I ended up in the hospital. That's where they finally found the right combo for me.
But no more Adderall for me. Ever. My pdoc prescribed Strattera for my ADD, which is a non-stimulant. It works pretty well. I'm happy with it.
Please be careful. Adderall can be the devil in disguise. It makes you feel so good and then it tears your life apart. Best of luck to you.
