I have a few questions.... I do not have CF but i REALLY do have stomach problems. I called my doc today to get an appt. my problem has been going on for a long time, (over a year) long time to me!!!! anyway, i will get horrible cramps ( worse than labor pains) vomiting, sweating and these attacks normally occur om the middle of the night, they keep me up for a few hours and after i finally am able to actually have a bowel movement i am exhausted the entire next day. I have not been diagnosed and my fear is having a colonoscopy done, which i know is what my doc will suggest. Do you think it could be caused from diet, stress or what, it used to only occur about once a month but now it is more like a couple of times a week . I am afraid to eat because my stomach hurts and i do not want to be up sick all night again... Any suggestions?????
