Sara;
Yes I have seen it and have heard of it too. I get that way if I cook with too much Garlic. Even takeing extra Vitami E that is seperate from my multi vitamin. Try to think if you have added any supplements to your eating plans. Or Herbs.
Also have you've switched soaps, dedorants, etc even little things like fabric softener sheets changing them too and bath soap and laundry soap can make your skin more senstive and thus changing body orders. But I go easy on garlic now ,and only take is in my multi vitamin I take each day no extra vitamin E.
