Anyone else gone gluten and dairy free to help improve symptoms

Hi,
It has been suggested to me and i have talked to people who havegone gluten and dairy free that has helped their symptoms. justlooking for anyone here who has and interested if it has made a difference? if it has could you share some menu's or give me some ideas? and how long did it take for you to see improvement? i have some general ideas on what to buy but looking for more before i head out. its been suggested to me because i have hypothyroidism which until recently has been out of whack, hyperplasia with possibilityof autoimmune gastritis, possible sjorgens syndrome and maybe lichen sclorus. im waiting on specialists to confirm but i have to wait for appointments which is so hard. its kind of like starting fresh. in 15 months of being sick i have gotten little help so im traveling 3 hours to boston where i can get better help its just hard waiting for these appointments.i am seeing a naturpath dr in a few weeks never been to one so not sure what to expect but i think he is better than who previously i have seen. sorry to ramble just hoping someone here relates tome and can help me out. thank you!
