I completed Fast Day 13 on Monday (24th). All plain sailing really except that I knew the rest of the week would not follow my usual pattern due to visitors staying over and various eating out arrangements.
I did actually sleep really badly. I fell asleep after 3am and got up at 6.30 as I couldn’t sleep and felt uncomfortable all over. Bad weather meant that my football game was cancelled the next day also so I was unable to complete my usual routine which I found quite irritating as I think combining it with a fast day seems to work well.
