^very true RPD89. If you take them for recreational purposes be careful. That stuff can definitely get out of hand in some cases. However, I have never felt better than I do now taking both my Adderall and klonopin together, as I have suffered from both ADHD and Social/General Anxiety my whole life. I am one of those people that actually needs to be on both stims and benzos, because of those disorders I have and have also tried many other non-narcotic meds to help with them before jumping straight on to amps and benzos. But if taken in a recreational sense unprescribed, it can lead to problems for sure, real quick. Thankfully I am able to be responsible with both of those meds I am prescribed, but even people who are prescribed that stuff, sometimes especially those people, can get way outta control with them and end up in a bad position.
To the OP I would like to know how much experience you have with Xanax and Dexedrine so I could possibly chime in and help. It could possibly be that those drugs just aren't something that agree with you. I know some people don't get a whole lot from Xanax but do from other benzos like valium or klonopin, and the same goes for amphetamines like Dexedrine, some people get more out of the other stimulants out there like Ritalin or focalin more than the amphetamines.
