Congrats!
Funny story: On the eve prior to my wedding, I had an awesome baked salmon.
I awakened at about 3am sick as a dog. I couldn't believe it, because I was sleeping like a baby, and was suddenly very ill. I kept tasting that damn salmon.
No matter what, I couldn't vomit. I tried, but couldn't.
Finally, about 2 hours prior to the wedding, I was feeling mostly better...but, I was dead tired.
When we had gathered prior to the ceremony, one of the groomsmen was totally goofing with me. He was saying "Last chance...there is the door...you have a choice"
It was funny, and kept my mind off the nervousness.
I wasn't really nervous for myself-- I wanted it to go well for my bride, and was angry that I became so ill.
What was more funny was my wife's brother (also a groomsman) kept saying "...man, I'm really nervous..." while chain smoking. He was serious.
Yeah, we had a good time...
