I don't know about your weight/diet, but if I wake up hungry, it's because I really skimped on dinner. Maybe your meal isn't big enough? When I used to wake up early, the general reason was because of medication I was taking - ironically to sleep (Ambien in this case). What medicines do you take? Do you It's also possible, as other posters have noted, that you might have any number of conditions. Sleep apnea was a factor in my problems, but can only be diagnosed/treated by a doctor. And finally - though it doesn't sound like your case - it's possible you might be trying to get more sleep than you need. Now 3-4 hours is almost certainly not enough, but if you sleep 8+ hours some days - and you always shoot for 8 - that might be more than you need. Try reducing your "goal" sleep time, until your "sleep efficiency" increases (this is a classic treatment for insomnia)
