So I was taking 5 mcg of cytomel a day and alternating 50/75 mcg of synthroid daily until last week. A week ago i went on 1 grain of armour (60mcg) and i am starting to feel a little more tired. I was told the 1 grain of armour would be sufficient but i don't believe so. It is not as easy to get out of bed the last 2 days and i was falling asleep on the couch in the evening the last 2 nights after sitting down for a few mins. The dr told me the 1 grain is equal to 100 of synthroid but i do not believe that at all. I was taking @ 75-80 altogether with my synthetic combo and now on 60 mcg. I understand that ratio is different on NDT of T4 and T3 but this is not enough. What do you all think?
