I can somewhat relate. I lost 30 lbs since March, and reached my goal weight at the end of August. I hadn't quite figured out the weight maintenance bit when I got pregnant, so I sometimes waiver between eating EVERYTHING and reigning it in and being more cognizant of what I put in my mouth. I continue to exercise 5x per week to balance everything out, and I think that it helps me mentally. I'm not paying attention to the scale as much as how my body feels.
Are you exercising at all?
