Lol I tried milk once because my dad said that, made it like 100 times worse lol just had more liquid coming up at night. The fat content it has makes it worse for me. Might work for you and my dad but mine is something far worse lol cant be controlled with tums or anything OTC
I then reccomend Pantoprazole (generic protonix) it is RX though. I also did find an OTC that had actually helped me, I htink it is Prevecid (I could be wrong about name). Don't bother with Omeprazole, barely puts a dent to the Acid. I really hate it and made me miserable.
About milk, I did drink 2% so dunno. Might try cottage cheese or yogurts a day to preemptively strike at the evil acid first. Regardless, hope it goes away! >_<
