Yeah, I was on a couple of different things two years ago, and did not like the side effects. That's when I upped my walking-and-jogging routine to more serious running, and it helped a lot. I figure if I can get rid of, roughly, another thirty pounds then I can stay off them for another decade or so.
Hypertension contributed to my grandmother's death, and I'd rather not go out that way if I can help it. :-P
