A week later???? This makes me think that it is not the Epsom Salt that did it but rather your need for E.S. - or more exactly your need for magnesium - E.S. is very reach in magnesium (utterly important for the bowels) and because candida depletes mag., it is important to supplement in huge amount (i take 3 X the recommended amount on my magnesium bottle) .
An enema is ALWAYS the best bet when you have bowel pain.
Shelley used to proceed without the E.S. (I am afraid I do not remember precisely how she managed). Ask her how she did it on her forum: http://www.askwhelley.com
She is a great resource, she has recovered from candida.
