funny, I usually think of it as the other way around now. when I have had c for several days, the only "cure" is a case of D. I do fiber (2 citrucel tabs at night), try to eat more fiber and drink omre water, and also watch the calcium/magenusium suplements I take so I don't go to far to too much calcium. But I also know if I do the hypno, I am much better overall.for me the key is to try to stay as regular as possible. not always an easy balancing act.nancy
