---YES! I have been experiencing nearly identical side-effects, and I have been on Adderall for about 7+ years. I have been having pain and tingling in my arms [not my legs, although that did happen about three years ago and went away] to the point where I can't sleep at night. I feel like my breaths aren't good enough- like I have to take extra deep breaths, and even then it's still bothersome. My mouth will often feel strange- not just dry mouth, but something else that makes me feel like I need to drink more water. I have the same mood/motivation swings that you mentioned as well. This has all happened in the past few months. I recently learned that my mother is bipolar [apparently mis-diagnosed as regular depression], which I understand is very genetic, and apparently [?] Adderall isn't good for bipolarism. However, while feeling down every now and then, I've usually [until recently] been alright and would have never considered ADD and bipolarism to be an interaction or problem.
Anyhow- PLEASE let me know if you find anything out on this! It's very confusing and frustrating. This is kind of random, but does Adderall have the effect of inhibiting the body's ability to take in certain vitamins/nutrients?? I almost want to describe some of my sympotms as feeling like I'm "missing" something.
