Appreciate your answer on this-thanks!

I have prepared myself since 2 weeks ago for my first flush later this evening. This morning I had six apples blended with some lemon juice. Didn't have anything else.

My question is: HOW MUCH WATER am I allowed to drink before 6pm (when I start the Epsom Salt and the rest of the procedure)?

Can I drink plenty or should I limit it? - I am a rather heavy water drinker. Plus, is it beneficial if I add some fresh lemon juice to the water I am drinking - to help soften the stones?

Thanks.
