ghinzdra beat me to the point. To add my thoughts, your symptoms sound a lot like delayed sleep phase syndrome. The root problem is not that you're sleeping too much (a healthy brain wakes itself up). The root problem is that you're not feeling sleepy early enough to get a good sleep.
There are basically three ways to deal with this:
1) Ignore the solar day. Probably not practical.
2) Use an alarm to sacrifice sleep.
3) Use zeitgebers and good sleep habits to fall asleep earlier.
3 is hard, but I've found it to be worth the lifestyle changes. 2 is miserable, I won't go back to it.

1-drink water (NO SODA OR JUICE) about 1.5 l
Dehydration and sugar-shock are bad for sleep and general health.
Quote:2-get a lot of light...
In the morning. Evening dark is
crucial. It should probably start about 12 hours before you plan to wake up. Maybe even more--the exact timing requires some experimentation. The beginning of dark-time is how I control my wake-time. Basically, instead of cutting my long day short during sleep time, I cut my wake time short by killing the lights.
Darkness means using only as much light as needed. Warm light is better than cool. Blue light keeps you awake, so amber sunglasses and candlelight can provide enough light for reading while still allowing you to get sleepy.
Quote:3-move
Again, during the day. Exercise before bed can cause insomnia. Currently, I take a 20-minute walk in the morning sunlight without sunglasses after breakfast.
Quote:4-give up on caffeine/alcohool/tabaco
Tobacco's always bad. Caffeine at breakfast only, no more than 2 cups. Alcohol rebound can wake you up at night--avoid with dinner, but a small amount's okay at lunch.
Quote:5-practice power nap 30 mn
Napping only works if you have a healthy sleep-wake cycle to begin with. Start waking before your alarm first, then try napping after lunch, if your work schedule allows it.
Quote:6-avoid fast sugar
Again, sugar surges play havoc with all kinds of body chemistry.
If you still need an alarm clock because there are things you
have to be awake for, prefer a dawn-simulator to sound-alarms.
All that said, music is great for going from groggy to awake. It's just that
you should turn it on, not your alarm clock.
Oh, and an advisory: the first month or two will be very tough as you recover from years of sleep deprivation. I experienced very long sleep periods, fragmented sleep, evening insomnia, and morning insomnia. Eventually, short days cut down on my sleep requirements, but this took a while a while.
Totally worth it though. My mood has improved immensely (I've struggled with low-grade depression on and off for years) and I've lived without an alarm clock for over a year.
