drinking less than the amt recc. in the book doesnt change the ratio of the salt to water that you are taking in. just the amount of water that is going to flow through your system.
i really dont know how people can fit all that at once in thier stomach. for me i am not a big eater. like i eat a bunch of little things during the day. i think the volume of water recc. is just too much for my small stomach to handle and thats why i felt sick when i tried to drink more than half.
also after 20 minutes i start sipping at more water to make sure i am properly hydrated. i really dont like the thing and i opt to skip it. its for addition internal cleansing anyway.
