Hi Cake
welcome to my world,,my tolerance is down,,you can swap out to another,but once you have a reaction to one opiate,,your bound to have it with another and even with hydrocodone[vicodin]],, if you start haveing a rash itching on your hands or feet,,thats a liver toxicity,,the liver is trying to off load the med because it is in a weaken state.thats the boat that im in ,,your liver may be healthy,a blood test and aldolase test will tell you how your livers doing,,opiates are brutal on the liver and they are horrifying to detox off of,, talk to your dr,,see what he thinks,,but id run the blood work,,good luck to you,,,bobber
