Hey Andy - sucks about the basement, glad the PRSes are safe, and sincerely wish you well with your health issues. I've had moderate reflux over the years, and although it's not super painful and disruptive like yours, when combined with some of my anxiety issues, the symptoms were WAY too heart-attack-like for comfort. The little purple pill, and a radically changed diet, have helped. Complete cold-turkey on the caffeine was required, which was brutal at first. Even decaf has enough caffeine to bring on symptoms for me, but I can fit in a small piece of dark chocolate here and there without too much pain.
The lifestyle change has been a bit tough with the wife, but the kids are young and have been actually really supportive, and I have noticed my "good habits" rubbing off on them, which is a nice side effect. I eat what I need to, substitute or skip some things, get some dirty looks etc. sometimes from the wife - but at the end of the day, we're not much good to anyone if we're not around, eh?
I did find that my reflux symptoms were much more closely tied to my anxiety than anything else (which is probably why the caffeine has such an effect). Once I got that under control, things got much better. I hope you get to the root cause of what's ailing you soon! We're here when you need to vent.
