I used to have the same problem with amphetamines and cocaine, and I assume that if I were to take way too much of either, I would probably have the problem again. With amphetatmines, like Adderall, I usually don't get too much of an axniety/panicky type feeling. It just doesn't have that effect on me. I will feel slightly euphoric on them, od what I have to do, and then gradually come down which sucks because I may get a bit of a headache and be a little crakny, but I odn't get any panic attack type of feelings. Normally, I could take anyhere betwteen 30-60 mgs of Adderall and I won't get freak out. With cocaine, when I was younger (in my teens) I could do it with no problem. For whatever reason (and a large reason why I do coke now like once a year if that is because of this very reason: I would do some and then get overly concerned about my heart rate an whehther I was going to live, etc. etc.
