This is quite worrying. It seems to show that this doctor does not understand how to work correctly and safely with pain meds. It is severely difficult, and can even be dangerous to reduce pain med dosage that much at one time, without any tapering.
I am also being pressured ("encouraged") by my rheumatologist to reduce my meds, and I have been very worried about the question of tylenol damage for some time. The issue is so complex, and it is not any exaggeration at all to say that the way this is approached and handled can either improve or destroy a person's quality of life. You need to be reducing your meds no more than one pill at a time, per month. At the same time, you could add something that my doctor prescribed, which is the time released morphine-sulphate at a low dose, taken just twice a day (lasts roughly 12 hours), in addition to a lower dose of the Lorcet -- but it's a bit irresponsible, and certainly very uncompassionate, to take you from 6 to 2 pills a day. That big of a drop all at once can potentionally throw you into a bad flare, cause anxiety or panic attacks, or depression.
I really would go back to your doctor and attempt to talk to your doctor about this. Try to be calm and confident, so that he or she is less likely to condescend to you or treat you like that famous monster with whom the majority of us are hit over the head with sooner or later, the drug seeker. Stand your ground, and speak with authority: your life is not possible without adequate pain medication right now. Ask him to prescribe another drug.
I'm worried about the tylenol issue too, and my liver is now showing very slight damage. I've long been frustrated that the drug companies ever decided to put tylenol into so many of these medications. Why? Tylenol certainly never did a thing for me. Doesn't make any sense. But we may be the ones to pay for their bad thinking.
The time release morphine sulphate does not have tylenol in it, and it is helpful. It's actually fairly mild, but does last, and in combination with another med it really does help. There's also something called Vicoprofen. It's oxycodone combined with ibuprofen instead of tylenol. I'm on a different type of drug now (stronger), but when I switched from vicodin to vicoprofen some years back, it really did work much better. It's hard on the kidneys too. No drug is without side effects, and we need pain meds in order to function. It's a compromise.
I also take a supplement with milk thistle in it: that's supposed to help detox and support the liver. I'm hoping it can help a little. Best of luck with everything.
