Hi Princess and welcome.
Coincidentally, one of the reasons I started on this journey was to lose the weight in time for my oldest son's wedding....in August of 2010...but on the 28th instead of the 1st. I gave myself tons of time, of course and have about 7 months in order to lose a little less than 8 lbs. But let's say his wedding was today.....even though I'm not exactly at goal yet, I look SO much better now...fabulous, in fact, IMO. May not be at goal but there is a HUGE difference.
So is 6-7 months enough time to get to your goal? Well, not sure if it's exactly enough time, but it sure is enough time to look fabulous for your wedding, whether you technically reach goal or not by then.
