Hey Dol - are you realising that you will be nearly, if not at, target by then? Its about 10 weeks away, and if you loose maybe 3.5lbs a week, you will be ten lbs away from target - so maybe it'll be about time for maintainence by then? Or at least you should be okay doing AAM or 790 for that week.
Personally I'm going into maintainance at the start of December, have promised my H that I will go out for dinner for his birthday, and have pretty much every weekend till Jan booked up to do something, so I really don't want to be on SS then. Also I just know that I would be too tempted to cheat otherwise, which for me would lead to eating a load of rubbish, rather than being sensible. Am going to try and follow a mix of maintainance/ GI/ healthy eating through xmas and the new year, and see where I am come Jan. Will be keeping a VERY close eye on my weight however!
Good luck whatever you decide hon.
