I do "disconnect" when I'm at work. Most of the time I'll be working a 5-8/9 hour shift, so that's a good chunk of my day to be disconnected. Other than that, I try to have my phone on me at all times so that I can be connected to the net if need be. I like to RP as well and I've got a partner I talk to on Skype all the time, so I try to be available for her when I'm not working.
