Update: It's now 2336 hours and I just finished a story of which I am not proud. OTOH, it's written without a single word of dialogue and in five different viewpoints within 1,400 words. Bizarre and not terribly imaginative but it works. That's either nine, nine-and-a-half, or ten depending upon whether or not and how I count that trivial little short-short.
The spark and energy that I felt the first several days is not back but I'm determined to write anyway. This wasn't great literature... but it was a little fun. I also found out a few things about poison in the process of researching this. I may never feel safe again.
Did you know DSMO will open up the pores? And if you pour that and some cyanide into a person's shampoo, it should poison the user. I'm not absolutely certain about this. I have no desire to conduct an experiment.
