It's easy to run your AI's too high, which will cause extreme estrogen suppression
making you lethargic - and is a bitch!
Estrogen plays an important part in supporting serotonin... this is one of the body's
principle neurotransmitters, which is vital to... "mental alertness and the sleep/wake cycle."
Interference with this neurotransmitter is also associated with chronic fatigue syndrome...
so you can see how it is to fatigue specifically.
It's just one of those things that a lot of people get wrong at first, because you hear so much
info on excess estrogen... and very little talk about the benefits of the proper balance.
I was guilty of this in the earlier days and had no idea what was causing the symptoms.
