I am currently on 10 mg of Percocet every four hours, but will be out by tomorrow and my doctor is switching me to Tylenol 3. I was wondering if anyone out there has any experience of going from Percocet to T3s? My doctor preferred Vicodin, but I'm allergic to it. I'm concerned it won't help my pain, but I'm not all too sure how bad my pain is right now as the Percocet keeps it at bay pretty well. My doctor's nurse made it sound like the T3s will feel like I'm not on anything at all, so I'm really nervous. Thanks for any input you can give me on this.
