No writing last night. I should be able to get back to the desk tonight - there's less on the go.
I always suspected that problems would start to arise after I was about two or three weeks in to my program - I was basing this hunch on similar experiences I and others have had with starting to work out.
Sure enough, that's when I started hitting personal and other-commitment obstacles to sitting down and writing.
The fact that it wasn't surprising doesn't make it any less frustrating, though.
