Why is that unrealistic? The 12 hours off we get between reserve periods is when we're supposed to rest, isn't it? If you're expecting a call around midnight, then why not plan on going to bed around 4pm, and when you get the call you've had 8 hours rest. If you don't get called, then find something to do around the house/crashpad, go grocery shopping, watch tv, etc during the night. I do stuff like that all the time. Even on my days off, it's typical for me to stay up all night until mid-morning or so, then sleep during the afternoon/evening. If I have to do something during the day, then I adjust as necessary, but I NEVER plan anything when I'm on reserve. Come on, I get a minimum of 13 days off a month, it's not like I can't plan my personal life around that, and I'm a commuter.
