Don't think about the big picture too much - just keep looking ahead to the next half a stone, and it'll seem so much more acheivable. Make sure you take time to celebrate each little victory too, you've worked hard for it after all!
I usually decide on a little treat to look forward to when I meet each milestone - last time it was to get measured for a new bra (which I did), but it could just be something simple like an evening of pampering at home (hot bath, glass of wine, manicure)
Thankyou everyone, all that support makes it so much easier for me!
Loving the advice Alex a little pampering treat every half stone, now that's achievable!
