In my opinion you should try to stay away from pills. Self control is what you need and I think you are doing pretty good for now. Do increase your calories a bit though as someone said itss too low for your weight.

Increase your Protein to at least 1g per pound. That alone will keep you from eating junk food 'cuase you won't have time to eat anything else. Drink ton of water and run run run..
