Does sound like a huge change. Hope you get some answers from those in the know. I would be concerned myself. The dose you are on is pretty high to start, I know you can get hypo symptoms sometimes if you are actually too high. Maybe something is missing causing you to not absorb properly? just guesses from me I am afraid. After a long time I ended up stable at 45 mcg T3 only, compounded twice a day. Not sure it is perfect but we shall see. I will have a full panel done soon. Have you had a full panel? something like this Thyroid Hormones | Meridian Valley LabMeridian Valley Lab My Naturopath wants me to do this to get the full picture. Sounds like working in the blind right now.
Started Primal June 2012 at 148.5lbs, and 5' 1", reached goal weight in 5 months.
Lowest weight 93lbs - too thin. Now stable at 102lbs much better weight for me at my age.
Primal, minus eggs, dairy and a myriad of other allergens.
