I first developed IBS-D in 2002 after my father died. Lived with it for several years before finally get a diganosis from a gasto dr. After a colonoscopy, several test, celiac testing he told me I have IBS and I have to learn to deal with it. Told me to take extra fiber which only made the situation worse. I was so discouraged and disappointment. My brother in law also suffers from IBS. He had been taking Digestive Advantage. I finally decided to try Digestive Advantage. I took 2 caps 1x daily. After about 7 months this made a huge difference in my way of life. All this time I was trying to deal with my husband's deployment to Afghanistan and trying to raise two kids who were active in sports. As you all know living with IBS-D is very difficult. The Digestive Advantage made the episodes not as frequent. Still would be severe but not as often.My husband was deployed again last year. I know that stress is a major contributor to my IBS-D. Well it started disrupting my life in a major way again. I was missing school plays, school functions. I am very lucky that I work part-time but it was getting to the point where I was missing work. I would go to work and then leave an hour or two after getting there. I used to have the episodes at night - now they are randome and all over the place. I thought my hormones were causing havoc. I am not trying to come across as complaining. I have read the post on here and I am grateful that I don't have it worse. I can't imagine at how long some of you have suffered. Anyway after missing out on my kids lives and my own life I made an appt to see a dr to see about trying to go to another gastro. I was very suprised at how knowledgeble my dr was about IBS-D & C. The point to all this is that she prescribed Dicyclomine (Bentyl). She said she had great success with using this. She said that most patients only had to take 1 or 2 a day. Side effect drowsiness.. I would like to know if any of you have tried this medication and if it was helpful for you? Any other side effects that you have had? Any information or input would be wonderful.
