Intermittent fasting is supposed to help your body turn over all the lining in your gut. Sorry I don't have a link to share ATM but autophagy helps your body clean out all the old stuff because it's not busy digesting food. I've been doing it for 2 months and lost 23 pounds, but I have a better one. I stopped drinking about 10 years ago because it made me feel terrible even with just one drink. At Thanksgiving this year, I had a few glasses of champagne and then the next day 2 beers. Normally this would put me under. But amazingly I had no hangover whatsoever. I'm not going to return to drinking, but just wanted to share how well fasting works. If you work hard to replenish your gut bacteria, give yourself a boost and try to incorporate IF as well.
