Unfortunately its very common, do a search. I'm fitting a solar charger (lighter power points don't work with the key out, so you have to wire it in to a permanent live) to combat the issue.
Other solutions are to leave the earth off the battery, turn off the alarm or leave on a conditioner on all the time.
You should get longer out of it at in the summer when its not so cold.
Its always worth getting your alternator and battery checked, halfords do it for free.
I get about ten/eleven days out of my new battery and alternator, I've got a couple of threads about it with lots of owners with the same issue.
The general concensus is its the alarm. This weekend im going to put the meter on it and start pulling fuses to confirm it. Its a right pain.
It isn't completely across the board of owners but I suspect the way it was last driven dictates if you get any more time out if it.
