As someone who worked from home for awhile and then, stupidly, took a job that paid more but required a drive into the office, I have to tell you to *not* take working from home for granted. The commute, the office politics, the hassle of having nothing but a microwave to cook your lunch... all these things that I did not have to deal with suddenly have become the bane of my existence.
I envy you. Find a more comfortable place than the kitchen table. Be sure to use the extra time you have(seriously, you have at least two extra non-commute hours than the average worker) for social activity or at least getting out of the house.
Obviously I'm not you, so I dont know how flexible your employer is, but chances are you have built up some goodwill over the years. I would sometimes leave the house and go for a walk, go fishing, go to a movie, whatever... just to get out of the house for a while during the day. Just limit it to about 2 hours max, and only when its a slow day. Hopefully you have enough common sense to know when that kind of thing is appropriate and when it is not.
