Thanks for sharing your experience, I appreciate it. What I've seen from the 24h studies I've is very similar to what you describe, BP is highly variable throughout the day and nearly everything you do (or don't do) has an influence on it. One saving grace, if you can call it that, is that BP responds extremely well to medication. I take a small pill every morning and my doc says so long I keep it up, I've nullified all related health risk since my BP is now in a good range. So something to consider if, like me, you never find an underlying reason.
