I used to eat vinegar like a maniac lol. It was so delicious on like salads and stuff. However, this didn't happen to me from the start. Eventually after like 4 or 5 years of this I started to develop similar symptoms. My nose would become runny, my head would start hurting and similar things. It eventually actually became really annoying lol. I went to a doctor and he couldn't exactly point out the problem. I wanted to go for a second opinion but so far time hasn't allowed that :( Anyone have any idea what this is? Or how to solve it, because I love vinegar I do not want to have to give it up completely.
