Trust me, you'll get used to it, and after a while, even your maintenance calories may not seem like enough. I felt exactly as you're feeling now when I first started maintenance. I was eating anywhere from 1400-1700 to lose. I kept adding in calories and still kept losing until I reached 2200 calories per day. Now, that's quite a few calories, and it should be more than enough for me. Usually, it is. However, there have been many times that I've exceeded those calories because they just weren't enough for what I wanted at the time. I really believe that even if my calories were 3000 per day, I would eventually find some way to eat up or exceed that amount.
Enjoy this honeymoon phase ---LOL!
(Not trying to scare you, but just trying to be realistic. Like bargoo said, though, maintenance is so individual, so I'm sure others will chime in with info about their experience).
