I used to feel hungry at night before I started losing weight and during the first few months. In fact, lately I've been picking up that habit again!
The way I overcame it originally was mind-over-matter. Even now, I talk myself out of eating by keeping busy with my drawing or writing (or assignments!). What I find to be my problem is that I always have to be doing something. For instance, if I'm watching a TV show that's getting a little tedious, my brain will think of food and suddenly I'm hungry! Sometimes starving! And yes, I will be thinking of chocolate or something sweet.
Drawing on suggestions that I've read since joined 3FC, my advice to you is to either a) overcome your cravings that you stop thinking about eating at night or b) eat, but do it in moderation and find foods/drinks that are healthier. If you are calorie counting, choosing better options is the way to go. I have drinking chocolate that's 99% sugar free and ice cream that, although slightly more expensive, is a lot healthier in calories than the leading brands.
