Hah Beer has a ph of 4.5 compared to Gatorade 2.9 and soda 2.0
Red Bull is 3.9
Distilled water 7.0
Home carb/distilled water and X20
Or
Safeway seltzer water (it has no sodium) in lemon lime flavor and put a shot of pure non concentrated juice such as orane/pomagranate/cranberry (no sugars added)
The seltzer idea sounds pretty good - I may try that.
