6 days ago I was having diarrhea and cramping. 2 days ago I took an anti-diarrhea medicine called "Imodium" with gas relief. I weighed 130 pounds before i got this, and I'm 5'11". After that I haven't had a single bowel movement sense only gas. Haven't eaten much except soup and crackers when I can. I have only thrown up 2 times, but after eating I feel like I need to but don't. I think it's just gas and have been taking "Gas-x" 2 last night and one as I type. My intestines keep hurting from cramps and pressure. I have included a picture here: http://i52.tinypic.com/2ciicz7.jpg . If its urgent I will go to the ER.
