If your weight loss is pretty much stalled, it means that you're in energy equilibrium: your calories in = the calories you're burning in a day. In order to get back into a calorie deficit and lose fat, you need to increase your exercise in order to increase your calorie burn and/or decrease your daily calorie intake.
I'm not sure how much exercise you're doing daily and whether you could bump up the intensity and/or duration to increase your calorie burn. That might be something to think about?
Myself, I had to stay between 1200 - 1300 calories in order to get to goal, so what you're suggesting sounds right to me. The calorie level you're at now is my maintenance range, so it's not surprising that you might be stalled out. So dropping it down might get your fat loss moving again. Just make sure that you're making every calorie count -- getting the most "bang for your buck" nutritionally -- then give it a try and see what happens.
Good luck and keep us posted!
