That's the only time I had the frequent urination. I would think if I had heart failure it wouldn't be two nights over a year apart, it would be continuous and worsening. The entire period from my 60th to the Middle of the Night stuff was during the period when I had knocked off riding, I started back the last week of last August. Rode indoors until the temperature outside wouldn't melt an aluminum bike out from under you - about mid-October.

Ever had too much salt? You pack on some extra water and at some point you body gets rid of salt and water together? No, I don't recall if I had too much salt, but I've suspected an electrolyte or mineral imbalance like that was causing both the weird pulse and the urination.

I also have that Benign Prostatic Hyperplasia (as do most guys at 65), or "prostate the size of Rhode Island" as I like to say. That makes me more likely to get up during the night, but I usually only get up once.

Just got back from my regular 13 mile, every other morning ride. It's nice that, at 65, I can see progress almost every ride. Getting a little faster, handling the headwinds a little better. Technically, I'm still 64 for another two weeks.
