Medical science these days is amazing. They can control nearly every chemical, cell and hormone in our bodies with little pills. They've even figured out how to alter the brain's chemistry to alter moods and stabilize seratonin levels.
So why can't anybody come up with an effective, safe appetite supressant?
Or have they, and I just missed it?
Sigh... I know it just boils down to self-discipline and a healthy lifestyle. Thanks for letting me rant a little.

Why no good cancer pills? Why no good pills to prevent AIDS??
Science can only do so much. I'm sure they are working on it.
But your last line hit the nail on the head.
