Tramadol
"Although I think it is great that people read up on medications that they take, I cannot stress enough how important it is to make sure this medication is prescribed by a doctor who has examined you, knows your biology and knows what meds you should take. Too many people lose their lives taking meds not prescribed for them, or mixing with otc meds or drinking alcohol. Be safe. This drug worked great for my back pain.  I am glad my doctor chose it for me."
