I'm not a great meditator, but I can usually sit still for 10 minutes each day in a simple practice:
"just close your eyes and watch your thoughts play like children."
Seriously, that's all I do, and it really calms me down and makes me feel better!
I started trying this idea of meditating when I have a craving for junk food, and it really helps me a lot. Then I drink tons of water afterwards to help flush myself out - I think that helps too!
