Hello all...I was on MS Contin for 20+ years (3-4 30 mg a day) for arthritis. Aug. 29, 2007 I took my last pill with the support of my husband, doctor, and boss. I first went through 4 weeks of pure hell, then several months of breathing problems, anxiety attacks, runny nose, cough, muscle cramps. It is now almost 1 year since that day, and I have been great for about 5 months...no more withdrawal. There is one concern...my doctor gave me ultram 2 months ago, and after checking on this drug, I've read that you don't give ultram to anyone after addiction to drugs like morphine. Today is Tuesday, and I took my last 4 last Sunday. Now, I'm afraid I'll have more withdrawal systems. I have no craving for any type of drug now, but I'll never take any chances again. Anyone out there have any thoughts on this? Should I worry?
