JC --
PLEASE re-read your own thread about this.
viewtopic.php?f=7&t=1397&p=17624&sid=a4132a87959c92af4fce232acf6c695f#p17624PAY PARTICULAR ATTENTION TO Q'S POST. You may want to discuss postponing your surgery with your doctor. I thought you already had your surgery??
A single non-nal drinking session, or even a few, will not dial back your progress. I had to be off for weeks (between two surgeries) so I speak from experience. It's not desirable, but it's not the end of the world either.
I can also speak from experience when I say that, yes, arthroscopic knee surgery is painful. Very. And I have very high pain tolerance. Effective pain management is an important part of recovery, because you need to get mobile asap and you naturally will resist this if your pain is not well-managed. But read what I posted in the other thread about pain meds and liver damage.
Perhaps more importantly, it is not fair to yourself or to your surgeon and anesthesiologist to gamble on whether the naltrexone is out of your system. This potentially is a nightmare scenario, and you would be responsible if you sandbagged on this critical piece of information. If you do decide to go forward, I hope you are straightforward with them.
Let us know how you are doing.
