pain
"Had surgery in 01, then I re herniated my lumbar discs.  I use a tens unit, pain patch, and lots of aspirins.  My doctor prescribed Ultram 50 mg 2x a day or as needed. Haven't taken it everyday because I get sluggish at work. Works great for the pain, but makes me VERY tired. Also, I wake up in the middle of the night and can't get back to sleep."
