Would consider asking about adding a small 5mcg dose of cytomel to the levothyroxine - probably need to decrease levo to 137mcg in this case. This does not always help, and many docs don't feel it's worth a try, but we've seen success in some patients.
Boy, I sure can relate to your symptoms. I am 2.5 years from pap/foll cancer. Just got all clear on labs. It took me at least a year to find my right dose. I am now at 150mcg levo and I take .5 cytomel 2x a day and this really helped me. My weight finally got back to normal.
I do still feel overwhelmed and tired and loss of interest. I went to a naturopathic dr for awhile and took tons of supplements which seemed to help, but hat taking so many vitamins. I still take the fish oil, vit B's.
I think getting used to a new normal after TT is what its about. Life can't be the same with no thyroid, it's a very important gland and it's gone.
I can say I feel much better than I did 6 months after my TT. It can get better, but it doesn't seem to ever get back to the way life was before. Maybe just acceptance of this new normal and celebrate no cancer.
