Eh this is iffy. Normally, I would advice to speak with your Doctor. However, I had a similar experience. I'll share my experience to see if it helps you but keep in mind that every-one's body chemistry is different. What works for you might not work for me and vise versa.
I was on Armour Thyroid several years ago for approx one year. It helped but it also hurt. Eventually I got sick of of feeling sick and tired. I stumbled across a book one day our of desperation that sparked the beginning of healthier times to come. The book is called GREENS FOR LIFE BY VICTORIA BOUTENKO.
I started by incorporating dark leafy greens into my diet daily for five consecutive days a week and taking a multi vitamin every day to ensure I was getting all the vitamins I needed. A salad to be precise. Within three months my Thyroid apparently began to work. The doctor was alarmed and asked me to completely discontinue my thyroid meds. How could I ??? I had been on it for one full year. I did some research and decided to gradually ween off. While gradually weening off I started drinking the green smoothies daily. Within another 3 months I was completely off of Armour Thyroid. and within about one year I felt normal. The same medication the doctor said I would be on for life I haven't taken in well over three years! I feel GREAT all thanks to a drastic change in food habits an life style changes.
So what I do now to maintain it is .....
-Get adequate sleep
-effectively manage stress
-Daily consumption of raw vegetables and green and little fruit
-Watch my diet!! (eating complex carbs versus white carbs, no sugar, raw veggies daily, adequate protein from plants and some animal not too much, etc
-Juice five days a week
-physical excersice but not intense
-balance life style
-Conciously choosing to be happy
