Hello
I'm a newbie as well. Good luck with your weight loss. You certainly have a fantastic goal so that should help keep you motivated.
The trick to successful slimming is to maintain the weight loss.
I'd suggest that after the wedding, you try on that beautiful dream dress once a month (except when pregnant!) to make sure it still fits, or post-baby etc nearly fits. I wish I had done that. I've lost and gained weight over the years, and I'm at my heaviest by a long way. Actually almost twice the weight I was in my 20s.
However, the scales are now going down, and if they can for me, they can for you.
Here's to a beautiful bride in a beautiful dress on a beautiful day.
