Four flushes in seven days is really excessive...especially if you are using Epsom Salts during each flush. Make sure that you drink lots of water in order to rehydrate and take electrolytes to replace those lost during the flushes. If you're dehydrated...which is likely after so many flushes spaced that closely together...you will feel more toxic as the concentration of toxins is greater. Loss of electrolytes can also make you feel bad. As for the pain...not sure what it is, but since it extends across your abdomen it could be spasms in your transverse colon...the bowel muscle may have become fatigued from the laxative effect of all the Epsom Salts .
