Congrats on the wedding!! I have been there too. I got married at 23 (5 years ago) and it was 3 months after my symptoms started and no one really knew what I was going through as far as family and friends. I too had to stop 3 times on the drive to the church because of the stress getting to my stomach. One thing that helped was touring the church or wedding site ahead of time and finding a private bathroom if possible. I found one and we labeled it for the bride and everyone thought it was just where I was slipping the dress on so it was embarrassing or anything, but it was good to have. I know stress is a trigger, but once you start walking down the isle so much adrenaline kicks in that my stomach was just fine. I made it though wonderfully. I had a code word with my made of honor when I needed help to the bathroom at the reception, and although I had to sit down a few times I never needed to use it. My husband was go great about the whole ordeal that it reminded me even more why I picked him. I don't know if you can take narcotics or even if you would want to on that day, but because of the constipating element they help me out a lot getting though important events and I have a prescription, but I know many can not take them. Good luck on your big day, and I have faith that that adrenaline will kick in for you and get you though it with your mind on your man, not on your stomach .
Kam congratulations on the coming wonderful event! I got married almost 4 years ago. Like you, I was worried about bathroom trips and sickness during the day. Like Fitzy said, I just prepared as much as I could, then went with what happened during the day. Like you, I cared about the marriage, not the wedding so everything was pretty simple (hey we were 38 and 40 the year we got married)---just make the rest of the day simple for yourself.
1) I wore thigh highs instead of pantyhose so if I needed to run to the potty, it would be less of a project. I also picked a dress style that was not too bulky in the bathroom (too late for that now, but remember that people will help you with your dress, they love that stuff!). 2) Ask for help and let people help! Ask someone to be responsible for the little things that day...I had someone else in charge of getting the programs in into the church etc 3) eat small meals all day so you keep your energy up, but don't have too big a gutful if you need to go. I asked the waitress for our table to save me a plate of mashed potatoes for later in case I was hungry again--she microwaved me a plate around 10pm so I could keep going. 4) Don't drink at the reception---I avoided anything after the toast just to make sure even though I know I usually handle 1 drink well. 5) Smile all day...it makes you feel better
Non CD wedding advice - 1) look at everyone as you walk up the aisle! It was so nice to see everyone smiling and I enjoyed them enjoying the day. 2) enjoy the "bubble" - after I took my Dad's arm, I went into this bubble that I had no control anymore and everything will be as it will be. ENJOY THE DAY!!!!!
