Well I have to say I'm very proud of you!  
MFP  is absolutely spot on with me so far ... signed up for 1/2lb per week  and that is what is coming off, lol.  Would love to see a bit more come  off on the scales but don't want to eat below my BMR ... just afraid  that it will start to affect my already quite low metabolism.
I would love to discover that by eating more I could lose more weight but it's just to scary to try!
How many cals are you eating now?  I think you are around the 1250 mark which is lower than me ...
Sneaky peek shows 10.13.5 this morning - desperate to see 10.13 on Thursday!
