Hi. My very first thought is that if you have candida, which I assume since you are on this forum, drinking beer is a huge no-no. Drinking is a no-no period, but beer is the absolute worst. You may as well be eating a loaf of bread. I had a very mild case of that vision issue for a short time when I was just overly toxic. If your liver is stressed, vision issues can arise. I'd suggest some things that have helped me recover - digestive bitters, Livatone and/or Livatone Plus capsules for liver support, chlorella, olive leaf or oregano oil as an antifungal.
