Why Can't I Sleep 8 Hours Straight?

[tgt]

I am a healthy person except cannot sleep 8 hours straight. I tend to sleep for 3 to 4 hours wake up then have a lot of difficulty getting back to sleep. I'll lie awake for 2 hours then have something to eat then fall asleep again for a further 3 or 4 hours. How can I not wake up in the middle of the night?

Note:
I don't drink coffee after midday
Sleep in a good quiet environment without anybody disturbing me
Have a good bladder and it's not because I need to go to the toilet
I am taking melatonine tablets an hour before sleep but that doesn't seem to help
There isn't anything obvious that I am anxious or worry about

You should consult a sleep specialist. Internet forums are not a good place to look for sound medical advice.

Agreed.
