So, for years now I have suffered from extreme fatigue and brain fog/memory issues. I had my testosterone
and thyroid checked, both were low. I on now on thyroid meds
and testosterone replacement but it hasn't made a dent in my fatigue and brain fog despite my levels being optimal now. I do have sleep apnea and use a CPAP at night but my numbers there are also optimal. Caffeine, and most stimulants, make the fatigue worse.
