Hi,. I developed food and chemical intolerances when the early rumblings of peri started nearly three years ago. Had to change diet & some toiletries (I avoid SLS & parabens). On a recent holiday, I tried a very small amount of a local liquor &, within a few minutes, my cheeks felt extremely hot & my body looked like I had a very bad case of sunburn! It took around 30 minutes for the redness to disappear. Strangely, my normally mild hayfever also became much worse the day this happened then it disappeared two days later just before my period started. It made me wonder if histamine levels rise before a period is due or is it just coincidence?
