I must say I do have a bitter/acidic/metallic taste in my saliva. I have ph test strips and I do test on the acidic side but not way acidic....definitely need to be more alkaline, I think. As far as "following" Montreal's diet I have been pretty darn close with the exception of substituting fresh wild caught tuna a couple of times for Salmon. I Drink 7-8 glasses of water a day, exercise, etc.etc. I also have a breath "issue" but was told it was caused by Esophageal Diverticulitis. So many ideas and thoughts to consider.......
