ireneo gives good advice. I had to wear one for thirty days prior to my pacemaker implantation, and there were moments I wanted to use it as a skipping stone when close to a river. I did, in fact, wear it when flyfishing one day... if I fell in the river, oh, well...
I went in every week to have the lead adhesives changed. Like Ireneo, I simply unsnapped the leads during showers and explained the signal lapses during reports.
That being said, it will record important data and answer questions, so try and think of it as your friend. There are times, I think, one simply has to put one's hands in one's pockets and endure some inconvenience to learn some truths, and this may be one of those moments for you. Hang in there.
Sleeping wasn't bad. I would wear some sweat pants or other comfy pants to bed and hook it to the waist band, pretty much in the center so I could roll to my left or right side. I slept well with it. Bathroom time - you'll figure it out, toss the monitor into your pocket if you have one or drop it down the front of your shirt. You'll find a way to park it while you go. LOL
