I work in the beverage alcohol industry, so drinking alcohol is part of my professional life.
Since my surgery journey started, I've noticed a few things that, like most J-Pouch stuff, seems to be specific to my experience. Your mileage may vary...
1) I don't want to drink nearly as much as I used to. Prior to surgery, I was a daily social drinker, rarely getting intoxicated, but usually had a couple of drinks per night, or wine with dinner. This doesn't happen much anymore, not because of any adverse reaction, but because most days I simply don't want it. Part of me wishes this were not the case, but I'm listening to my body on this count.
That said, if I feel like having a drink, I have a drink.
2) On a business related trip about 2.5 months post takedown, I drank quite a lot over the course of a couple of days. Because I was concerned about hydration, I had two glasses of water for every alcoholic drink I consumed and, while there was some serious hangover symptoms, the pouch functioned "normally" during that time, and I've taken to doing the two waters for every drink thing whenever I have a cocktail these days. It seems to help.
3) People telling you to stick to certain spirits over other spirits have no idea what they are talking about. Provided the spirit isn't sweetened or flavored with something post distillation, ethanol is ethanol is ethanol. And, if you're worried about it, gluten can not survive distillation, so all distilled spirits (again, unless flavored post distillation with gluten containing ingredients) are gluten free. Depending on the distillery, there is a slim possibility of cross contamination if wheat is fermented on site. Most distilleries won't go to the trouble of getting certified gluten free, but Maker's Mark is, and it is made with wheat.
4) I was a huge craft beer fan, and for whatever reason, I have lost my taste for it. I hope it comes back.
5) White wine, rose wine and champagne have been fine for me when I consume them, but red wine has wrought havoc, but that could also have been due to the meal that I consumed with the wine. Who knows, really.
6) The carbonation in beer gives me gas, but sparkling wine does not. Again, who knows why?
