Do you feel better since having the mechanical valve put in and what restrictions do you have besides drinking a ton of alcohol?
yes indeed I do feel better, but I was fortunate this 3rd time that it wasn't left too long before surgery, because the aneurysm drove the bus to surgery.
(btw, I didn't see you'd asked me a question because you didn't reply thus I didn't get any notification).
I also actually don't have restrictions, indeed I did drink in a "normal way" for the first 10 years after my mechanical valve but have had to cease because (and I suspect a dose of COVID here) I developed a tachycardia arrythmia (soon after getting a mild covid experience) which is now fully triggered by a standard drink. The most I can hope for now is to have 10ml (its pathetic isn't it) of a good Whiskey (Lagavulin 16yo) once a week.
Well I've lost more valuable things from my life than the ability to enjoy red wines and whiskey ...
The "you can't do it" list is composed by people who don't actually have experience and in many cases is demonstrably wrong. Such as eating greens.

The available evidence does not support current advice to modify dietary habits when starting therapy with VKAs. Restriction of dietary vitamin K intake does not seem to be a valid strategy to improve anticoagulation quality with VKAs. It would be, perhaps, more relevant to maintain stable dietary habit, avoiding wide changes in the intake of vitamin K.
so my advice is to make sure you restrict your readings on the matter to actual science ... while not perfect its far better than 99% of the fluff on the web.
