FWIW - I am considerably older than you and am on hypertensive drugs, a fairly mild regimen. I have seen the effects of exercise on controlling BP as I have gone in and out of being good about exercise and diet. I'm noting this primarily as encouragement in your strategy - I've found it all too easy to develop excuses for not running and keeping my weight controlled. The good news is that returning to the discipline has always helped - but I'd have taken fewer drugs if I'd been better, and I agree with your opinion on the side-effects.
So. Good work. Yes, it helps, yes, it is hard to keep going, and I'm glad to see this, not in criticism of anyone else's choice, but as encouragement to someone with a similar problem.
And, totally unrelated except to why I'm here at all, I've been enjoying Range of Ghosts. Looks like you plan to keep that up, too. Excellent!
