Yes indeed. I tend to get energised at the beginning of a project, then go overboard and get massively exhausted about 3/4 of the way through. Didn't help, with the last story, that winter was setting in and it triggered arthritic symptoms, so I was labouring under what felt like a half-ton weight. Still not feeling well, but this new story was pretty much all photographed in the summer so the 'heavy-lifting' has mainly all been done and I can keep warm in front of the PC instead of racing up and down stairs to my SW storeroom/photo-studio.
