As for the piss thing, I'm not surprised some people have brought it up. For some guys, it can be because of prostatitis, which is usually just from habit (but it can rarely be bacterial). You can inflame it with too much alcohol, caffeine (Dan!), sitting or sexual activity. Doctors prescribe antibiotics often, but that doesn't solve it.
I've got a touch of it in the past, where I'd have piss about 7-10 times in 24 hours (compared to the usual 3-5). I can sleep through the night just fine, but during that period I had to wake up in the night, too. It's all good now.
Overactive bladder, prostatitis and stuff like pre-diabetes (Dan!) can definitely lead to this a bit. For prostatitis, try Prostaphil-2, which is a great natural supplement that helps with any inflammation down south.
In general, limit caffeine and alcohol, try and stand at your desk more, and leave your dick alone for a while. All good.
