One thing I would consider doing is testing your liver to see whether it is damaged or not. I had UTI like burning after ejaculating and urinating a few months ago and then it went away as quickly as it came. I did some testing at that time and learned my liver was slightly damaged. Once I started to heal my liver, my symptoms improved.
Beer is just about the worst thing you could have; I wouldn’t plan on drinking for a long time. I haven’t drank for about 14 months myself. If you do drink, beer/wine is the worse and potato vodka is the best. I would not start to cheat on the diet until you are nearly symptom free.
I wish you luck on the diet! We have a very strict forum diet if you are interested (email able900) where we don’t even eat rice or nuts.
