Just a brief update for now. Added the 3/4 egg yolk to my evening meal last Friday.
That was a mistake, big time. Saturday was unbelievably bad. Seriously thought I would not make it to the end of the day — just so incredibly crampy, twitchy, and extremely agitated and anxious. Must have some sort of issue with choline or acetylcholine?
Anyway, after about 8 hours of sheer hell, I did a thiamine shot, and for the first time that day I was able to calm down a little.
Will follow up more soon. Thanks again CP for trying to help. :)
