Good for you Flop! Although, I'm not married, my sister just got married March 08, we live together, I was in the wedding party, so I got to hear about it all, and was there in the planning LOL. Just like the rest of the guys said, enjoy it. Try to not get all caught up in the minute details that don't go precisely as planned. Your fiancee probably is holding the reigns to the wedding for the most part, and will want everything just so. If you guys keep in mind that it is about you guys starting your new life together, you'll notice that it makes things a bit easier. Plus, it all goes by so fast, you probably won't notice. Hopefully, you guys have some sharp people in your wedding party who can deal with any "crisis" that may come up. In fact, just incase they don't know, tell them they're going to deal with it, and solve the problem should it arrise. With you feeling nervous about the whole thing in general, when you and your groomsmen are getting dressed you guys will be excited, and being guys, toasting, having drinks (don't get trashed). It all turns out great you'll see.
