I am going to try the lemon detox for 7 days, as I think after many hours of research it is my liver that is toxic and causing all the problems (even though I'm young and look relatively healthy!) I am also going to use grapefruit seed extract in a neti pot for my nose as I think this will kill any possible candida or fungal problem in their that might be causing postnasal drip. I hope this works but I'm very encouraged by your post.
