Good job guys!
I too started at 310, but on 7 Dec 2009, so you have a week or 3 on me. Weighed in today at 272, shooting for 220 by 01 Nov 2010, but would be happy at 240. I'm 6'2", and never have been petit.
During the week I am pretty serious about eating and excersize (3 days @ gym & 3 days with 3 mile walk) but on weekends... Lets just say that I know Guinness Draught is "only" 125 calories/bottle.
When I look at the graph for my weight, I can easily pick out the weekends!
