I've been using ACV off and on for years. I usually stop using it due to it causing me really smelly gas! Like that sulfur-ish smell that is oh so pleasant.
I can even be cleansing and juice fasting and still get the bad gas. As soon as I stop the ACV, the gas goes away.
I am pretty sure that I'm Lyme positive and I have a big problem with the ammonia/neurotoxins from the die off of the bacteria. Could the excess ammonia and the ACV combined be causing the horrible gas?
