Is this possible? I had used them on and off over the last five years. I never went on binges or stayed up for more than 24hours. I usually would take them early in the morning in order to work on a school project or do some type of task that involved lots of concetration. I used pretty good quality crystalized street meth and pharmacuitical dexadrine snapsules over my time of use. Though I have been relatively amphetamine free for over a year and a half now (excluding two occasions I used dex for exams!). I do feel that there might have been ramifications from my use...I am not as hyper as I used to be (which I actually liked) I'm more burnt out almost and now I am wondering if maybe this was just from growing older and maturer instead of the drugs changing my brian chemistry. And as of late (last four months or so) I have been developing minimal social panic attacks....they come and go very quickly, are manageable, and really have no triggers (I find that very odd). Not to mention, my ability to focus on things is lacking (In school and even in normal conversation) I tend to zone out or get a distracting sensation that makes it hard to focus on things visually (is that odd?). The sensation seems to center around where the bridge of the nose connects witht he forehead (maybe i need glasses, but that feeling seems to come and go with no real triggers either). I am really starting to wonder if this is all shit I have just built up in my head or wether this is the result of drug use. I really havn't read of any of these symptoms from other amphetamine users...I also would like to mention, if this was caused from the drug use why did it take almost a year to start happening? Any ideas out there, or simillar experiences?
