@lampofred you dont think its from NoFap? Are you having any sex to fulfill your needs? Are you still "drowning" yourself in progesterone? If so there might lie your answer. Hans Selye noticed that if he gave rats an very high dose of progesterone it would put them into a completely comatose state- he thought they were dead.
I don't think I've ever been healthy enough to consistently have an actual sex drive. I can count on my fingers that number of times I've had an actual sex drive, but since methylene blue pretty much eliminates my libido, the majority of my "sex drive" has been from nitric oxide. So I don't think the low energy is from NoFap.
I don't take high doses of progesterone anymore unless I am just extremely stressed, but progesterone actually increases my energy (and also increases my sex drive), so I don't think the fact that I used to take lots of progesterone when I was stressed has anything to do with it either.
Dr. Peat also said that he thinks low brain progesterone is involved in fatigue because progesterone is what allows you to relax, turn off energy expenditure, and accumulate energy so that you can work again in the future. So progesterone isn't the cause of fatigue, it's actually too much brain estrogen preventing me from being able to accumulate enough energy that is at fault.
