My headache seems to have abated with switching projects and drinking two large glasses of strong green tea (about a litre). Of course now I'm so wired I haven't a chance in heck of sleeping for a few hours. Think I'm going to try to get some more work done on the VoIP project. Hopefully won't get the headache back for my trouble.

Maybe it's just a matter of working on something I enjoy, but I feel far less stressy now than I did just a couple of hours ago (despite the jittery caffeine feeling). I have correspondence to get to as well, but I can't read the comments in OpenOffice, so I'll have to do that tomorrow morning. Oops.
