Found another substance with the narcoleptic effect: Shiitake (Lentinula edodes).
Is it the immune boosting properties that causes the fatigue?

My endocrinologist never believed me when I told her that taking Vitamin D3 makes me extremely tired. And Shiitake contains the precursor of the plant version of Vitamin D (D2, Ergocalciferol) Ergosterol.

Maybe it's not the fish oil itself that causes the tiredness but the VItamin D in it, the algae oil has also added Vitamin D to emulate the fish oil.
So the underlying cause is probably a virus infection or an auto-immune disease.
Or am I maybe feeding a yeast with the Ergosterol as it is a component of their membranes.

But I doubt it as urine test for D-Arabinitol was negative (although there are non-producers like Candida glabrata and Candida krusei) and a stool test for Candida species was negative.
At some time I thought I had Sarcoidosis (I'm sure it's a disease that is related to a modified Tuberculosis bacteria) because that's a condition that is also worsened by Vitamin D.
