It all depends. Are you happy where you're at or do you want to lose more? If you don't want to lose any more, you should gradually (very slowly) raise your calories. Everyone is different and you have to play around to find your "sweet spot". Perhaps you'll be able to go up 200 a day and maintain-- but it could be more or less. If you would like to lose a few more pounds and aren't too miserable eating the number of calories you're eating, then keep doing what you're doing with perhaps a small indulgence here or there.
Good luck and congrats!
Lots of great advice here so stick around!
