Best of luck jenhen
I saw your recent post on emma's diary (what a fabulous read eh, she should write a book about her weight loss experience, or her life in general !)
But back to you, as this is your post.
You're right this is much harder when it's not your first try.
I lost 3 stone in 2004, let the weight creep on again (but not too much) so I started again in 2006 loosing another 1.5 stone
I'm at my all time worst weight now, I am changing my life as of today though. No more excuses.
Sorry to ramble on!
Wishing you success, hope you'll keep posting with your progress
