welcome - I find that making sure I check every day is a big help. I also love joining challenges to push myself to stay on plan and see the weight loss build over time.
If you haven't been there yet, check out the 100 lb clup
http://www.3fatchicks.com/forum/100-lb-club-55/ - for people trying to lose 100 lbs (or get from the 200s into Onederland) It's a great and very inspiring group of people who support each other to achieve these goals.
