I've been doing that lately. Thats why I've sold my forum, real life is more fun and fulfilling than sitting on a computer all day. When you own a busy forum you feel like you HAVE to check in on it all the time so even when you are enjoying your life away from the computer or your phone, something in the back of your mind is telling you to go check on things and make sure everything is okay.
It will be difficult to stay away from the internet for a very long period of time. It is not something that I am thinking about at the moment. Being on the internet has made me enjoy life more and staying away from it won't be easy at all.
Really sorry to hear of your health problems... it's a sad day when Dr's orders mean we need to leave the communities we enjoy, but it happens and your health comes first... best of luck with recovery and hope to see you around in the future!
