Success(?)
I took 180mg of Allicin + 750mg of Activated Charcoal 3 days ago.
I felt slightly sick for 2 days, a certain soreness like from cold, except it extended through the whole digestive system.
3rd day the symptoms were gone but I was a bit irritated and a worse mood than usual.
Then, on the night of the third day I woke up with the kind of deep unsettling pain and unhappiness I only have known from the days when I was severely depressed. The kind where when you feel it, you know something is going very wrong.
I took my entire supplement stack at once, everything that had the slightest chance of helping: Caffeine, Theanine, Gelatine, Thiamine, Thyroid and Niacin. Normally my engineer sensitivities would tell me to only take one at a time to be able to tell the effects of each apart, but this time I wasn't going to take chances.
And to my surprise it actually worked! I went outside for 5 minutes and when I returned the symptoms were already subsiding.
That said, this experience did change my view on antibiotics a little. I think that the body knows best how to manage bacteria populations without disrupting the metabolism. If antibiotics were the answer the body would metabolize them on their own.
Of course, I don't want to dismiss the effectiveness entirely, it does seem like that single dose has already cleared up the starch sensitivity. The question is just at what metabolic cost.
