I'm going to talk to my primary physician about referring me to a gastroenterologist. I've been suffering from sporadic but severe constipation for almost a year. Sometimes I go for long periods of time without having any issues and then I'll go for like over a week without, well, going. I try to eat the daily recommended amount of fiber or more each day and I love prunes and prune juice, but this doesn't always keep me regular. Since it tends to come with a lot of indigestion and sour stomach, I've been thinking that it's IBS. I'll keep a record of how my tummy is for the next few weeks until I can get in to see someone, thank you for the suggestions here.
