Calories at 6 months?
I never went over 800 calories while losing weight (and still drop under that in maintenance when trying to drop a couple of pounds). At 6 months I was just before my first goal and was averaging 800 calories. Some people only maintain at 1200...

I ate more calories than most people on here (I was blessed with decent metabolism), but that said, I didn't get up into the 1000-1200 range until I was a year out.
if you're still losing OK on 800-1000 a day, I'd just hang out there for awhile. I'd have to go back and look, but I'm pretty sure I was in that range from about 6-12 months out. If you need to drop back a bit on calories to keep the loss, then do that. A lot of people on here stay at 600-800 that first year.
