Hi Scarymary
Personally, if I was you, I wouldn't go as low as 1000 calories, at least not to start off with. To me, that seems, way too low.
I would look at a calculator (you can google these) to see what calories you would be recommended for your weight/height.
You haven't put your height on your profile (or at least I can't see it) but I took the liberty and put in your weight and a guess height of 5ft 6inch (at a different site i used for weight loss) and it calculated that you should be on 1590 calories and still be able to lose weight successfully on this. I know that must seem high, when you are considering 1000, but I would give the higher calories a go (even if you don't go to the high end scale of these) and see how you get on in the first few weeks. You can always change it, when you know how it is/isn't working in the next few weeks.
Also, I know your wedding seems not far off (congratulations, by the way) but I feel, if you go too low with your calories, you'll end up either feeling unwell, or you'll push yourself so much that you'll end up giving up. Give yourself realistic goals that you can work with, and you're more likely to succeed.
Also, try to add some exercise into the regime, which will help with the weight loss too.
Good Luck
