Kristi,
Hey girl, I didn't know you were planning on getting married . . . congratulations!!! Maybe quitting smoking could be a present you give to your fiance, although, I find that doing it for yourself is #1. I'm sure the stress that goes along w/planning a wedding isn't helping out your "situation" (quitting smoking) any.
It will go just fine! Trust me, I had the WORST wedding rehearsal, I was in shock the day of the wedding, believe it or not, when I walked down to the end of the aisle and my dad gave me away, I looked at my husband and said . . ."It's not too late to run . . ." I was in shock during the whole wedding until I got to my vows, then I cried . . . it'll be fine. I wish you both the best!
Anyway, I did try the wellbutrin, didn't do much for me.
Keep plugging away at it, you'll get there.
