"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&#039;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&#039;t get back to sleep."
