My son got married last year, and this is how I coped with the IBS and the wedding.Two days prior to the wedding I had very mild, belly kind, meals. Things like baked fish or chicken, mashed potatoes [whatever it is that is belly kind to you]. The day before the wedding I continued in this vein, only making the portions smaller and eating a bit more often during that day. That day I also began with my Lomotil. I take it only as needed, but I figured I may be 'needing' it, so I took a full dose [normal dose for me is one tablet unless that doesn't work, going then to two]. That morning I had a good breakfast of belly kind foods [toast, cereal] and took another a regular dose of lomotil, and right before the service I took an immodium.No problems whatsoever. I was worried that as the girl of my sons dreams was walking down the aisle to become his little pixie of a wife...I would be running back up it. Didn't happen and we had the best time. Now I had constipation two days after the wedding, but to me...it was darn well worth it!Congratulations on your wedding. It will be beautiful, you will be fine. It's your story to write and your memory to make. Remember that, and remember to not think of it as stress, but as excitement. Sometimes a mental boost as small as that can make all the difference in the world.
