Moderation is the key word, you will never be 'drunk' again.
However each person react's differently to both coudamin and alcohol.
I used to drink heavily before surgery and since surgery my INR has been rock solid at 2.8 or thereabouts. I home test. I'm 6ft 4ins, Male, 125kilos.
I was interested in the effect alcohol had on inr so i had a couple of glasses of wine and tested inr the day after, repeated this process until i got to a happy medium which was that i could drink a bottle of wine with no affect at all on INR or my 'drunk' status.
I am happy with this.
So i class myself as being able to drink a bottle of wine, or 4 standard bottles of beer with no affect to my INR (i have tested a lot).
I have on 1 occasion done this every night for a week whilst on a work trip with no affect on INR (tested every 2 days).
I have on a few occasions drank 50% more than outlined above with no affect on INR (tested the day after)
I have on one occasion drank a fair bit more (larger glasses not paying attention) and INR jumped to 3.5 the day after so adjusted coudamin and didn't drink for 3 days.
I don't drink spirits.
I only drink white wine and lite beer normally, probably 4 glasses of wine or 3-4 bottles of lite beer normally twice a week. On the odd occasion i will creep over this by 1 or two items.
Use this information as you see fit, it's not an endorsement to go out and drink what you want, nor does it validate any 'sub-question' you may have been asking that i haven't picked up on....it's purely an example to show you how a 38yr old responsible father of two has approached this subject area and how it's worked for me. I could get a stomach ulcer in 2 years time and be told how stupid i was but thems the breaks, risk benefit analysis exercise is what you need to undertake.
Hope the above gives you another viewpoint to consider.
