Luckily I am good to go once I am vertical, however painful the opening of my eyes feels each morning. Hot shower and tea and as long as I keep moving I feel fine. Which is weird, I guess, but a really good thing.
The fatigue definitely shows in other ways: yesterday I was carrying C's socks to the living room and instead sat on the couch and began to put them on my own bare feet. Putting the open jam jar in the cupboard instead of the fridge. Beginning email only to save it and forget completely about sending it later on, imagining that I'd finished my reply. I had a hilarious one to share and of course it's gone from my mind now! So many more. Unsettling, some, and humorous, most. I hope, should I ever get consecutive hours of sleep again, that things will turn around... If I have a fourth (fifth) pregnancy, I'm done for.
