Hia Slimslow,
Congratulations on such a encouraging weightloss this week. I am roughly the same height as you and am 11 stone 1lb just now.
My BMI is 25.1 and I am about a size 12, which I am very happy with (having never been one, even as a young adult).
I would have loved to have buddied you, but I will be following your progress with interest and wish you continued good progress!
Keep Drinking The Water!!!
