I juice fasted again yesterday. Woke up with 5.5 PH saliva, and urine about 6.0. I still do not understand how my ph goes down when I had 3 alkalizing drinks and green foods and juice all day. I feel no different than any other day. Some muscle and nerve pain. Can anyone explain this? Then I can eat alot of grains and have a 6.5 waking up ph the next morning. I dont get it.
