I have an app on my phone called sleep cycle. When I go to bed I turn it on and stick my phone on the bed under the sheets. It monitors movement and how well you slept and is supposed to wake you up in a more refreshing way. It doesn't really. Ive always hated getting up in the morning and this is no help whatsoever. But the best thing about it is the Info it gathers about your sleep and the graphs it produces.
You can input sleep notes before you set it and then it will show how things effects your sleep pattern.
In this graph you will see the effects of 'worked out' on my sleep. I should point out that 'worked out' is my abbreviated code words for 'wanking myself off before I go to sleep'. And this takes place practically every night. Lol.
But the others are real. Interesting how alcohols works isn't it? And look how much sleep I get at he weekend after a good night out. Getting up in the afternoon has got to stop though I think. My weekends are turning into bed and booze
