I drink 1 tablespoon of apple cider vinegar everyday, in water (four years now).

I've now forgotten what acid reflux is (used to get it bad).

My guts work better now, since I started using it daily, than ever before.

The first link I came across, so delve deeper...but I did quite a bit of research myself.
(make sure you use organic stuff- looks a bit cloudy and settles).

Good luck matey.
