I'm upset that my TSH levels are so low. The roller coaster of rotating doses between 112 to 125 puts me on edge because of the longterm impact on my heart and lungs and digestive system etc. Well, my whole body suffers. My levels are so low today, my endo wants to increase me to 125 again but I told him I wouldn't do it unless I could rotate the doses every other day. I wish I had never started thyroid hormone.
