Inability to Sleep / Insomnia

I thought getting up early yesterday, cycling 18 miles and only eating one piece of toast and half a bowl of pasta all day would mean that I could get an early night and get my sleeping pattern back to normal.

No, I went to bed at 1 and couldn't sleep until 5, when it was getting light outside. And have only just woken up.

Do not want.

I slept for 1h, somewhere between 3 and 5. Feel like a raisin.
