Ultram and sleep

I was prescribed Ultram for chronic back and neck pain because I had been on Vicodin for a long time but did not want to be on a strong narcotic long-term. Ultram is effective, but i have been on it almost a year and if I run out and don't happen to have any more, after about 12-24 hours I start sweating and I feel weak and can't sleep, plus legs twitch uncontrollably. I guess all pain meds have their problems.

Drove 500 miles from home...forgot to renew my ultram. Doctor would not renew without me coming in (have taken it for over two years). After 3 days could not sleep, my arms and legs would jerk uncontrollably, I wanted to cut them off. After six days I went to emergency. They gave me a five day dosage of Ultram. After one day back on...everything was back to normal. Over the phone my doctor told me to take Motrin!!! As soon as I see him (today) and get a prescription,,,I will change doctors.
