I just got put on a low dose of Adderall and found this topic interesting. I mean, technically it's a stimulant, right? Now, my fiance gets really tired on this stuff to the point of wanting to go to bed an hour after a dose. Me, on the other hand, simply feel neutral. I'm not really more awake or anything like that, but I'm also not dead tired. I'm just focused on one thing at a time, for once. I don't know if that means that I truly have ADD or what. Now, I also suffer from PTSD, depression, anxiety etc.. So far, I finally don't feel really depressed and my anxiety is more in control. I don't know if those disorders have anything to do with the effect of this drug. Can anybody explain this?
