I was started on T3 two months ago. Once I began the new med my levothyroxine was decreased from 200mcg to 150 mcg and added T3 at 5mg twice a day for one week and increased to 7.5mg there after. In the beginning I felt great but now I feel like I'm all over the place. Today I o.k. but the next day I'm tired and sluggish. I have mood swings and slight anxiety that all come and go without warning. How long will it take for my symptoms to level off and the energy to increase and remain consistent?

    It's time for a blood test to check levels. I suspect your endo reduced your T4 too much when he added T3. 7.5mcg T3 is equivalent to 22.5mcg T4 so by reducing your T4 by 50mcg you may be undermedicated and this could be why you are tired and anxious.
