Been Constipated Ever since I quit smoking 1 year ago? Today I've got really bad Cramps in my stomach walking?

Congrats on quitting smoking! That is a hard thing to do! As far as the fiber pills, I really dont think those do much as far as making you go to the bathroom. They may make you a little gassy but thats about it. I know smoking makes a lot of people go regular, and when they stop, they obviously aren't going to be going regular anymore. There is this tea that I drink (i have the same problem) its called "dieters green tea". OR smooth move. The dieters green tea has a NATURAL laxative in it, and it isn't harmfull to the body. I would try that instead of the fiber. If this problem keeps up, you might want to suck it up and go see a doctor. It could be a parasite or another intestinal problem. Yes, paying out of pocket will suck, but knowing will be good. AND they have to let you make a payment plan. Make sure you are drinking plenty of water, ESPECIALLY if you are taking fiber pills. That helps a lot with keeping yourself regular. Do you drink coffee? That always seems to jump start me as well.
