When a person is "VERY" Acidic and in "VERY" Poor health, they may need to go real slow with small amounts at a time!
It may be Best that they get all of the drink mix at the same time and use more of the Lime water in the mix, but drink smaller amounts of the total mix each hour thru-out the day!
What may be happening is that they have so much Toxic Waste and Acids in their Lymphatic system that any little bit of Acids like the ACV and Lemon juice starts to purge the body of those Toxic Waste and Acids!
What may also Help them very much is to do the bath soaks, but for short time periods between Hot and Cold and also use the Hydrogen Peroxide spray over their body before and after the bath each time to help Neutralize the body Acids!
For the skin has the "LARGEST" "SURFACE" "AREA" from which you may react opposing Electro-magnetic Energy Charges against and this may allow for the Greatest relief for solving of problems with Toxins and Acids removal from the body of any method which I know of!!!!!!!!!!!!
And it may be "VERY" Cost effective, compared to any thing else used!
She may need to start out with the simple foot tub soaks just for the feet, so as to direct the removal of her Toxic Waste and Acids out thru the feet first and work into the other as she gains strength and does not get such bad reactions from the Toxins being removed from her body!
Also one other "VERY" "IMPORTANT" idea may be to start taking an Enema to clean out her colon, so that her Digestive system may have a fighting chance to start working properly again!
Of course the "MOST" important thing for her to do, may be to "STOP" eating all of the "JUNK" foods she has been eating which may have caused her body to get into this shape in the first place!
