Perhaps, maybe also take a break every 15 mins or so. Walk around the room or something. And perhaps maybe don't over do it on the amount of time you spend online. Sometime I find that working in a "9 to 5" sense seem to be sufficient. And don't log on in the evenings as much and when I do, it's usually in just an "in and out" basis just to check few things. Otherwise, I'm mostly logged on just during the daytime, before supper and would relax a bit in evenings after a "good day's work". Just some constructive advice.
