Hi there,
I saw your post below regarding this issue as well. So you do 2 enemas a day on a regular basis? Why is that? Do you have issues with constipation? The runny nose and sniffles sounds like a cleansing reaction. If I were you, I would work on getting your bowels moving regularly and save the enemas for emergency situations. They can be very useful but you definitely don't want to become dependent on them. And yes, using them too often can definitely mess up your electrolyte and mineral balance. Moderation is the key.
Doing three in a row is okay. You would use much more water if you were to get a colonic or colema. It is using them day after day, that can create problems if you are not careful.
