Wow Charlotte, I don't know how you manage such long fasts. I really wouldn't be able to go that long without food or caffeine.
I did from 6.30 last night till 8.30 this morning without food, so guess that's 14 hours but I slept for 8 hours of that, lol!
Hope you're feeling a bit better now that the weather has cooled down a bit. It was so hot at the beginning of the week, you must have really struggled even with the air con.
