dr.lams talks about progesterone. there are problems with progesterone i do not remember what exactly may go wrong. dr. lam has an article on that.

pregnenolone has no negative feedback. it does not mess around with hormone production.

Klauss

-Huge digestive issues; was always bloated, stomach did not work properly, etc. (interesting zinc supplements helped a lot with stomach issues; zinc affects digestion);heartburn
(later used betaine HCl)Most of digestive issues were cleared after Dr Wilson program. Check my posts i put here description.

-Bad brain fog; could not concentrate at all. it felt like a sponge in my brain that prevents me from thinking straight.

-Always tired; did not want to move. it would take me about 10 minutes to get my bag from car parked downstairs.

-muscles lost tone, shape, became weak.

-anxiety. it felt like situation is so bad and the end of my life just around the corner.

-puffy face, pale skin very unhealthy look.

-hair became really fine, like baby hair and changed colour to copper blond, bad to touch. No real pattern just all hair on top.

-eyebrows fell out. about 1/3 of inner part left

- sleeping problems. would wake up at 4 -5 tired and bad, repetitive thoughts would take over; and i had to go to work.

-unbearable neck pain (where i had injury)

- no sex drive. just did not feel like that.

Probably it was stress. I had neck injury when i was young (probably from boxing). I was also in military in the East sleeping 2 hrs a day, etc. bad food. I had (other guys too) some stomach infection. It was treated with two Antibiotics one of them nowadays considered carcinogenic. I had digestive issues since that time (probably it happened that time). Because of the neck injury i had chronically running nose. Nobody could tell me what was wrong. Most of the chiro just bone crackers could not fix. It looks like they were afraid to apply necessary force. Finally, 10 yrs later i found a chiro who was a trauma surgeon in Eastern Europe. He fixed my neck. Lot of problems went away too: running nose, chronic heartburn. I was diagnosed with GERD - reflux disease. It was gone.
Then, problem at work started i had to move to another place, where the first bout of AF happened. Probably, I had AF long before just did not know about it.
