The whole point of the forums is to find out how to make these things work for you.
Telman would easily have figured out that you should take less epsom, or try a different form of magnesium. It ain't rocket science.
If you actually read the forums you would see that plenty of people do the flush without taking epsom salt.
And it's fairly easy to avoid dehydration by...
drinking more, soup, juice, whatever. It's not like people are bound in cuffs and forced to taek Epsom Salts and then not given anything else to drink. Hulda Clark flushes are just one method among many.
Your thought processes are still cloudy due to illness.
