Hi Rach - apparently its only a couple of pounds a month difference on 790, so if thats what you feel better doing, then thats the way to go!
Bea - DONT GIVE IN! You are doing *amazingly* well, just look how far you have come, and on LT all the way through. You must be an extremely strong-willed and determined person to have done this, just remember its not permanent, its a means to an end, and what a *fabulous* end!
Maybe time to do AAM?!
