I tried Brain Octane a while back, pretty sure it was in early 2015, before I went fully keto. I remember reading something about that it would dissolve many plastics.
Brain Octane gave me intense abdominal pain. I did some reading and found it wasn’t an unusual side effect. There were reports the pain was from your gall bladder. I reduced the amount I put in my coffee, used up the bottle and never bought another.
Fast forward to June of 2016 and I had not used Brain Octane in over a year. I woke up one morning with a pain in the same area. It came and went for a day or two, but then became constant. I had my gall bladder removed within a few days. The surgery report said it was pretty ugly. Two things they said were necrotic (dead) and gangrenous.
While I can’t prove it, I think the Brain Octane was telling me my gall bladder was going bad or already gone.
