Nothing does a top to bottom flush of the entire digestive system like the good old, bad old swf!!
My new improved version is almost painless:
Dissolve 2 tsp. UNIODIZED Sea Salt
in 1 c. drinkably hot water
Have 3 c. plain water standing by
Chug as much salt water as you can, chased by plain. Chug and chase til all water is gone. About an hour later it exits in dramatic fashion carrying everything in its path.
SWF is definitely a good idea!
Happy flushing to you both!
