Tramadol
"I was prescribed Tramadol for back pain because I am allergic to NSAIDs. I was taking two 50mg tablets per day and noticed that my mental state also improved while taking this medication. My anxiety subsided and I found that I did not get upset even in stressful situations (I work in HR which is very stressful for me). It's been a miracle for me since I deal with anxiety issues almost daily. It puts me in state of calm, but I'm still me. The only side effects I've experienced while taking Tramadol have been entirely positive. I wish it was prescribed for anxiety disorders."
