Low TSH & low free T3. Normal free T4

I had a total thyroidectomy approximately 10 years ago due to thyroid cancer.  Up until approx one year ago, I was able to take Levoxyl only to control my thyroid levels.  I had problems with severe fatigue and s/s of hypo- & hyperglycemia last year and was found to not be converting T4 to free T3.  Now, my latest labs show a TSH of .02 and a free T3 of 2.3.  My endocrinologist placed me on Levoxyl 100 mcg/day & Cytomel 5 mcg/day.  I have had problems in the past trying to increase my Cytomel any more- I had palpitatations, sweating, anxiety, etc.  I am starting to have s/s of both hypo & hyperthyroidism at this time.  Also, I have noticied an increase in hypoglycemia.  Do you  have any direction on what I should do next?

Maybe you need to lower your T4 a tad and add more T3. You can have symptoms of both if you don't have the right ratio between T4 and T3.  Where is your Free T4 test?
