I have been on hydrocodone for a year and two months. I am taking 40 mg. per day. Some days, it is adequate, other days, NOT. I do worry about taking so much Tylenol---which would be about 1500 mg per day. Recently, when driving, I grabbed one of my pills and put it in my mouth. I had forgotten to take something to drink on my way to the pool. I noticed that the outside layer sort of melted in my mouth and the inside layer was much harder and I had to chew it up. It made me wonder if I might be able to discern (through time---or someone here) which layer is the drug and which is the Tylenol?! I would prefer to dump the Tylenol and save my liver! Does anyone know the answer? I know it is weird to ask, but who needs all the Tylenol!? I wish they would make hydrocodone without that stuff!! I am not sure what I might ask for when I see the pain management people again. Or if I ask, will I be "flagged". I have some very nice PM people now. They seem to understand and are compassionate.
