Sleep - or lack thereof

My quick summary before probably didn't explain much and I don't think I've ever explained on here so here goes. I can't seem to get to sleep easily. This has been going on for a few weeks now. It takes about an hour-ish for me to finally get to sleep once I'm settled and ready to sleep. Once I get to sleep, I can't seem to sleep for more than 7 hours straight anyway. Now, most of you are probably thinking 7 hours isn't all that bad but if I sleep a night with only 5 hours, it means I can't catch up at any point. It also means that if I go to bed earlier and wake up earlier, then it'll take me another hour to get back to sleep and by then it's time to get up. There's been a few 5-6hr nights (have to get up in the morning and go do stuff. Usually TAFE, work or church.) and it's starting to get to me... Last week I went to see a doctor about it and he reckons it's just sleep deprivation. No kidding(!)!!! He told me to go to stop working and go to bed earlier which is fair enough I guess but it still doesn't solve the problem of taking an hour to get to sleep when it used to take me no more than about 15 mins and only being able to sleep 7 hours instead of up to 9 or 10 sometimes if catchup was needed. Grrr... this is why I'm tired, and probably somewhat sore. Just pushing myself to keep getting up and doing stuff that needs to be done... Anyway... back to it [/rant]
