Yes, my PH dropped some after I started the limewater but after doing the following 2 things I noticed it steadily beginning to climb up. I started taking greens powder in water immediately after taking the limewater to increase alkalizing minerals. I use KyoGreen. I also increased my Apple cider vinegar/water drinks in between the limewater drinks. Instead of having only two tablespoons a day of the apple cider vinegar in the lime water, I am consuming two more cups of water each with a Tablespoon of Apple Cider vinegar in between the limewater drinks, so that makes a total of 4 tablespoons of apple cider vinegar a day instead of 2. Although the PH seems to be climbing up and I would like to be positive and optimistic that the PH will stabilize at a higher number after these changes, it is too early to say. I am keeping my fingers crossed.
