I am really sorry that someone did that to you...those people who stole them are the readon why so many doctors are not as willing to prescribe pain pills to those of us who really need them. There is an herbal medicine that you can take to help you with the withdrawls. My friend is a neuro-herbalist and told me about this herb when they were "experimenting" with my pain meds. It's called Kratom and many drug rehabs use it to calm the withdrawls. Here is a link...it does have a disclaimer that it's not for human comsumption, but there is no side effects by taking it orally. It will give you a nice calming effect and relieve your cramping and nausea, so much so, that you may like taking the Kratom over going back on the opiates. I have been using it for almost 3 weeks now and I love it!
