Had a really awful night, got up to the bathroom 3 times, had four sessions of light on and reading (Nick should be really glad I'm in the guest room!) and saw most hours pass on the bedside clock! Managed to get up and have breakfast at 8, but went back to bed at 10 to catch up on sleep and didnt wake up till 1pm. I think this is the result of over-exertion - it is my body telling me it is stressed.
Tidied around the kitchen and could 'cruise' around the work tops without a crutch. Tried a tentative walk across the kitchen space, but I am limping a lot without the one crutch.
