I always end up getting woken up by someone or something
Seven hours EXACTLY? Do you hypnotise yourself to wake up after seven hours?
I would but I find that once im awake... im awakeI never time my sleep but id guess at about 12-14 hours. I often sleep for 10 hours at the weekend, any more than this and i feel more tired than i would have on 8 hours sleep.
Can you not just go back to sleep?, i just turn over the pillow to the cold side and I'm out.
It is quite easy to do! If you are destined to get up at say 7 and you go to bed at 12, your body can be, unless you are completely nackered, very good at waking you up for around 7 +/- 15 mins
