Looking-Well, here's something else to confuse you more. I used to have the same symptoms as you--painful cramps, loose stools, and D. For six years I took medications that decreased in effectiveness as time wore on until nothing helped. Around the beginning of February, I cut sugar from my diet completely. Cold turkey. It was hell--truly a physical withdrawal--for a few days, but afterwards, I felt better than I had for years. No more cramps, no more D, and no more fatigue. The fatigue had gotten so bad last year that my doctor thought I might have MS.I haven't had any cramping or D except for a couple of weeks ago, after I stupidly ate a large candy bar and had three days of cramps, D, and vomiting.The saliva in the mouth sounds like what I used to get sometimes when the cramps got so bad that they made me vomit.I strongly recommend that you try cutting sugar from your diet. I have also cut way down on wheat and corn, especially corn syrup. It's worth a try.Debbie
