Thyroidectomy-6/11. Feeling very tired. Tsh was recently. 05, free t4 was 1.8 (.0-1.7). Dr says I'm sub clinically hyperthyroid? Why so tired then?

U need second opinio. You are clinically hypothyroid, being tired. Even though chemically you are hyperthyroid. There are other tests which can be run to better refine your condition.
