"i have ptsd and anxiety disorder. i have been on bupropion hcl er xl 300mg and clonazepam 1mg teva. both medications taken together are terrible. my symptoms are memory loss, anxiety , tiredness, problem sleeping, panic attacks and depression. i feel like the bupropion causes anxiety and my new panic attacks. yes losing weight is great at first but i&#039;m in need for changing these medications. watch yourself make sure it&#039;s right for you. also headaches or migraines."
