Any chance of pregnancy? ~MM
I would advise a visit to your MD and ask for a Complete Blood Work up, A thyroid panel including TSH Free T3 and Free T4, and a Test for Blood Sugar. The fatigue could be a drop in blood sugar or Thyroid imbalance, Do you eat sweets often, sometimes when people eat a high sugar diet they crash in the afternoon and early evening. A complte blodd work will tell in most cases. Good Luck FTB4
