thanks so much for posting this question - I am currently wondering this too. My nathapath said the same thing - she has got me drinking apple cider vinegar diluted in water 3 times a day, along with grapefruit juice to drink once a day.
I have also started using Preseed - do you think this will help with balancing out levels?

i have just had a quick look at Ph strips - one website mentions it tests saliva -what should we be testing for this purpose? Salvia or CM?? would it be realiable? I do not have an appointment with FS until Feb but do not want to wait that long.....

what foods have your nathapath told you to totally avoid??
