Ultracet and itching

I began taking ultracet for undiagnosed backpain a little over a year ago. I'm over 6 foot tall and weigh over 200 pounds so I take 2 pills before each work day. It has been a miracle drug for me in helping with not only the back pain but all sorts of pain that comes with being a waitress. Unfortunately, Ultracet makes me very hyper, talkative and somewhat euphoric and I can no longer go to work without it. I never take it on my days off and I believe that when I take it for a string of days in a row that my body stops producing as much adrenaline and I feel very tired and slightly depressed. It also causes a lot of itchiness. Never mix this drug with cold and flu medicine, it made be very ill! I am not bothered enough to stop taking this medication but to potential users be wary of its potential side effects.

Originally prescribed Ultracet(actually generic Tramado/apap) for arthritis pain. As instructed, I took two pills at night and one in the morning. By mid-morning I was ill--vomiting, dizziness, extreme fatigue, some itchiness. The arthritis pain was diminished though.
It also gave me weird dreams --black and white television stories super-imposed on colorful dreams. Those were actually kind of interesting, not scary.
I don't think this is the right pain medicine for me.

I took the reccomended dose of Ultracet (on an empty stomach, unfortunately) at night, and was awake for 2 hours trying to relieve myself of the terrible itchiness. Once I had gotten to sleep I had no trouble, and the pain in my knee, which I had taken Ultracet for, was gone. However, when I awoke the pain had returned three-fold, and so I took another pill...mistake. I could not stay awake on the ride to school, and fell alseep for my entire first period. The nausea ensued about 15 minutes later, and I could not concentrate at all. By third period (around 9:30, 3 hours after taking the pill) I was trembling and could hardly walk; I couldn't have told you my name. I began to cry uncontrollably, and continued to fall asleep. I had to be escorted off-campus and taken home, where I slept for 4 hours. It began to wear off around 3:45 (more than 8 hours after the pill), and now I have horrible nausea. This is the most horrible drug I have ever encountered. Does anyone realize how badly this affects people?
