grats on toning up!!! that's always important as well as weight loss =)
Hmm... as far as pre-wedding advice... I had an AMAZING time at my wedding because I didn't stress out. Give yourself flexibility, relenquish the need to control every detail and just enjoy it! If you have people who you can delegate little tasks to (my aunt was so wonderful and took care of lots of little details) then you don't have to stress out about them. The day of the wedding, all I had to do was wake up, shower, throw my stuff in the car (which my aunt had set out the night before with a checklist), get my hair done, grab some lunch and then head to the church to get dressed. We played everything simple. And that made it beautiful and authentic and us.
Also, expect something to go weird or be wrong. We had a bat fly through the sanctuary during our wedding processional. No big deal! Everyone laughed, the bat found its way out and we went on. While the few days before the wedding i had a minor little spat over where we were going to put the head table in relation to the dancefloor - it really didn't matter. and once i told myself that, it was all just really great =)
