take some laxatives and see a doctor if nothing happens.
Too embarrased to go to the doctor? let me give you a reason..
A few months ago my lecturer who's a nurse was looking after this patiend who was totally constipated for about 5-6 days. The stool couldn't go down, so guess what passage it took instead?
Yeah, that patient was given the wonderful experience of vomiting up faeces.
That's not good, drink more water, excercise, and lower your junk food intake. Those chemicals really fuck you system up sometimes. Your body is having a hard time with all that crap in your body.
