If you have a gut issue - which imho is likely based upon your brief description - be sure to have the test which also checks for parasites etc. (it’s comprehensive...and expensive. >$400 out of pocket).
Otherwise, you may be wasting your time, and the symptoms will reappear. We’re all unique in some respect genetically and symptoms will vary. In my case it manifested in adult acne (among other weird symptoms), overlapping also as a reaction to foods I now enjoy (save for one poison I avoid perpetually: Palm oil).
And, btw, it will take much longer than 3 months to permit gut healing. Fair warning. I hope you achieve your goal.
Good to know. First manifested as a bromine allergy
