Anyone ever have this happen? Sooo long story. When i was an infant i was allergic to milk and sugar. Got dehydrated and parents had to change formula. Currently 46yrs old. Only allergy is red cedar. Spring 2021, i had a violent diarrhea reaction to peanuts and peanut butter. Tested the theory for 3 weeks every time the contributing factor was PB. Anyways, middle of August i started eating PB again with no issues. Anyone else had this type thing happen?
