Hi Louise,
Good Luck on your first week, and well done for making a start. I've got over 100lbs to go too, but it is possible. The VLCDs work really well if you stick to them properly and I can even say I'm enjoying mine this time!
Hopefully we'll both be on here for a while - and losing all the time! It is a great place for advice and a friendly chat.
Good Luck
Nicki
