losing weight

So lately I've been focusing on losing weight. I lost 7lbs in 14 days. just by cutting out snacks, soda and coffee, no diet pills here! Only thing is I still have about 20lbs that I want to lose and I seem to have hit a wall. it's kinda discouraging when you've done so well and then suddenly the weight stops coming off.

So what are some things that work for you guys when you're trying to lose weight? Some of the things I do aside from cutting out snacks and bad stuff like soda, is drinking a glass of water before meals. Also I've been running 3 days a week as exercise. I need to start doing some other stuff on the days I don't run but i haven't found the right thing yet.
