I mix the ES with just enough water to do an ES shot, then cbase it with water with a little lemon juice in it, ala like doing a shooter with tequila. You can suck on a lemon for effect too!!!
OR I mix the tbs of ES with about 1/2 cup of water/small amount of juice mixture, stir very well. Use a straw to suck up the crytstals off of the bottom first and the rest goes down easy.
I much, much prefer the grapefruit over the lemon but a mix of both is nice.
Brush your teeth before you go to bed. Chewing on gum or a piece of crystalized ginger or real ginger is nice too and helps nausea (which I never have had any).
You have a better flush if you eat virtually no fat during the day, but I have had flushes where I passed some stones when I ingested protein food or a little fat during the day.
I would plan on doing several flushes according to the hulda recipe then you can experiement. But some people do this, don't do that and have a poor flush and won';t do another because their flush flopped and they didn't even follow the recipe to start with.
Coat your bottom with vaseline, shea butter or the such the morning you drink doses number 3 and 4. If you pass bile that stings, it is from the liver getting rid of old toxic bile and that burns as it comes out.
Good luck to you.
