Actually Tammy, it may not be the thyroid with that level reading.  I was a 1.6 before TX and you are near that now. 
 Are you getting enough calories & nutrition?  Exercise also helps.  All trite advice but still reliable
I just started making coffee again in the morning and putting it down my PEG tube and the caffeine is really helping.
Chronic fatigue post cancer TX is a hard beast to figure out even though it is so common amongst us.  I do keep quite active but have to take naps - Hope some OCF family member here can be more helpful.
