Ready to explode symptoms and conditions

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!
