Oh man, I can totally relate. Do you have a bedroom of your own, at least? I used to write on my bed, which isn't the most comfortable, but if you prop yourself up with lots of pillows, it might be at least a bit better than the sofa.

They say you shouldn't work in your bedroom, because then when it becomes time to sleep you go into work mode, but I think it depends on the person. And even if you just change the environment a bit such that it signals "work time" or "sleep time" it should be better than having the television there and such.

It's been a long time for me, too.
