Glad I found this thread. I was looking up remedies for indigestion/reflux and cake are across ACV so I used 1 tablespoon in 8 oz water. 2 hours later, I’m having the strangest breathing sensation. It’s like, everything is super clear, huge breaths, but it’s still awkward and unpleasant. I’m feeling a little overstimulated as well, so I’m guessing this revved up methylation? It definitely doesn’t feel like my typical histamine reactions, but it doesn’t really feel like my previous overmethylation nightmare either. It’s calmed down a little the past 10 minutes, but I was ready for the ER again because that was horrible! Apparently, everything I take or eat from this point forward has to be from the focal point of methylation first.
