Ultracet and toilet

I have just thrown my ultracet down the toilet. I have severe osteo arthritis and in order to sleep I took the ultracet at night before bedtime.The first time I took it the next day I felt like I had the worst hangover ever and I could not keep my eyes open. I didn't associate the two since there was such a long time inbetween. A week later and I took two at bedtime again. Once again I'm throwing up and my head feels ready to explode. Never again!

have taken Bextra and when that did not help me the doctor gave me Ultracet but that made me very sleepy in the afternoon and I would sleep for two hours and have been having nightmares.
When I was taking Bextra I had this intense itching in the armpits,the groin and other parts of my body if I touched it and I noticed it also was the same with Ultracet....and so I threw the pills which the doctor has given down the toilet.....I looked it up on the Internet and found it is narcotic....Doctors dispense pills without looking at the side effects...
