Coffee was really the wrong go-to. Your poor liver!!!
Here is an easier way to drink the SWF... and thirsty? Chances are you were slightly dehydrated prior to drinking it. Drink WAY more extra water than you think possible during a cleanse to flush your system and protect your kidneys, and of course, to stay well hydrated generally!
It only took me four years chugging a quart of lukewarm salt water to figure this one out:
Dissolve 2 tsp. uniodized Sea Salt in ONE cup drinkably hot water
Have THREE cups plain water standing by
CHUG as much salt mixture as you can, chase with fresh. Chug and chase til ALL water is consumed. Voila! I've done it this way bunches of times and it works just the same for me, and I don't have to try to trick my mind that I am drinking "delicious broth" or some such nonsense.
The swf is NEVER yummy, never particularly easy, but it is an excellent flush of the entire digestive system, which keeps me coming back for more.
And yes, butt pee is de rigueur, with or without solids which may be hanging about in your colon.
