My question is Has anyone had a problem with taking glucosamine and condrontin with percocet and neurontin? I take 10/650 now 6 times a day and 1800mg neurontin a day. My doctor is having blood work done to check my liver and kidneys since I have been on the percocet for 17 months now. I keep hearing that the glucosamine and condrontin will help my back and neck from getting any worse but I don't want to mix and get into trouble. And has anyone ever taken the glucosamine and condrontin and got good results?
