constipation, drug induced
"Extreme withdrawal symptoms.  Chills, runny nose, cramps, pain, nausea, shakes, felt terrible. It worked well for first two days for a bowel movement but than stopped working as well.  The bad side effects continued all the time I was on the drug (2 months ). My pain Dr. was surprised at my reaction to the drug as most of her patients handle it well.  Insurance (UH) refused to pay for it after 2 months.  My cost was going to be around 400 a month not worth it for me."
