The good thing is you ARE staying determined. 3lbs is a good loss but like you say, inyour shoes god bless ya, I'd be expecting more -gosh in MY shoes I expect more so I understand why you're down about it.

You've been amazing, don't let a thing like 6lbs in a fortnight get to you because it really is fantastic. come on woman! Onwards and upwards!
