I have a mild anxiety disorder, and I have been prescribed Xanax. I very rarely take it, honestly only about once a month, when I am having a really bad day. The reason I do it is because I have I.B.S. and G.E.R.D. These conditions combined can make me feel weak and bloated, and give me severe chest pain. This is what causes me anxiety, and I'm pretty sure these conditions are not going away anytime soon. I have seen posts from people that use Xanax multiple times a day, and that can cause addiction/withdrawal problems; I am just wondering if I really do only take 12-15 times a year, can it cause changes in brain chemistry, etc. that I really should worry about? I would hate to find that upping my serotonin levels mildly on occasion might give me long term mental health issues.
