If you're worried about stomach acid dilution, you could always try topping up with a little apple cider vinegar mixed in with a glass of water after your meal? ACV is very acidic and is supposed to help with digestion, and of course water is important for everybody.

The best source I can offer off the top of my head is YouTube. Search for videos about ACV by Thomas DeLauer and there are a few there that you may find interesting.
