I had a bad back and leg pain. I am 73 years old. Doctor prescribed tramadrol, 50 mg, 8 per day. I took it for 2 months. Had epidural shots in back to relieve pain. Stopped Tramadrol, cold turkey for 1 1/2 days. Ended up in emergency room. Told to do it slower.Took 2 halves for 2 more days. Completely stopped 7 days ago. Is it normal to still have sweating , especially at night and to be very tired.
