I have Pain in my abdomen, Cannot eat large meals, last night I had to use the washroom 30 mins after eating and then made my self throw up a bit to feel good enough to get through the rest of my night as a functioning human... feels like I have urgency for bowel movements some times with serious cramping, I sometimes use the washroom up to 4 times a day... IS it from not eating enough during the days or what, I just want this fixed, everyday around 5:00 pm seems the worst... any ideas?
