Coconut oil is good for Thyroid but making me tired why?

Hi,

I have been struggling with Borderline hypoT for over 6 years now. Doctors here can't diagnose me, they refuse to believe that I'm boderline hypoT with TSH of 3.54. I have the symptoms: brain fog, fatigue, inability to lose weight, Depression and severe dry eyes.

As soon as I took coconut oil my dry eyes just disappeared, it was so dry that no eye drops/gel could ever help even for 1 hour relief. My body temp was 95.9 and after I took the coconut oil it became 97.5

But the problem now is that I feel so tired, even more than I already am, taking coconut oil. I get the best extra virgin GMP brands, but I don't know why it's making me so tired like that.
Any ideas?
