So I carried on yesterday as normal and did have a couple of palpitations during the day.
I'm very tired tonight as I didn't sleep well last night. I was very late to bed after being on the computer. When I went to bed I had the monitor clipped to my knickers and a diary at the side of the bed to record if I woke up in the night. I woke up loads of times and turned over and wrote it all on this paper! I'm sure that if I hadn't had to write it all down I would have just turned over and gone straight back to sleep again without being aware that I'd woken up.
So tonight I'm going to bed when I've written this.
