Hello and welcome. I think you'll find these forums a real help, theres everything here, help with the plan and syn values etc, recipies, motivation and advice, everyone is really friendly and theres always someone about to help out with anything.
You are right too, mostly we think of eating something nice as treating ourselves, but the real treat to yourself would be losing weight and feeling fab and being healthy!
I would be so pleased to get a treat like that!!
Good luck with SW and look forward to reading more of your posts!
