Geezum you guys replied quickly! Thanks so much.
It's settled, my friend's gonna bring the books in, I'm going to give it a try for in the run up to xmas. I can't see me gaining a lot over the holidays. I'm at work so I can control my snacking. i don't like turkey, don't really like gravy, ice cream, mince pies, puddings etc.... Gimme a gammon steak and cheesy mash on xmas day and I'll be happy!
