I bet your numbers would be *beautiful* if you stopped smoking and cut out the caffiene. Those are two addictions that are tough to quit, but it's certainly worth a try. I'm currently trying to work a food addiction (I love carbs) and it's been hell. I'm only 15 pounds overweight but my doctor has a gun to my head to lose it or he'll add nasty meds to my current regimen. I have pretty good systolic pressure but my diastolic, like yours, loves to get to 90, which it often does in the afternoon.
Stick with this website, whatever you do. You'll learn much more from your peers than you will from your doctor (although the docs are still a vital part of your wellness system).
Good luck!
