I had a few bad weeks. Part of the scheduled treatment was weaning me off steroids, and that proved to be a huge failure. I'm back on them, and two weeks in has resulted in a short chapter, posted, and a very short story that's in editing. If nothing else, I can think.
My goal, as I've said I think, is two chapters a month. I may get three occasionally, but I still tire easily. We'll see what happens.
