About a month ago, I had terrible food poisoning and suffered from it for a week. After that, I recovered from the illness, but stomach or something around that is still feeling bad. Especially when I am hungry or drink coffee, I do not feel good. I guess it is because my stomach totally became empty due to the food poisoning. The acid in stomach might be stronger than before. I have no idea this is related the problem, but I cannot taste good with beer since then. My sense of taste is really changed? Or just temporarily things?
