Nose Pitched high in straight and level flight!!

Hello Fellow Aviator's,
I was wondering if anyone could advise me on how I should go about fixing this problem.
I'm currently flying a Metroliner 23, At cruise altitude and speed, the aircraft is pitched up at the nose at about 15 degrees. Cruise speed is 0.52 mach and cannot increase the speed thinking it will lower the nose.
In spot plane view it looks very un-realistic.
On late final, it is almost impossible to land when you can't see the runway.
Is there anyway of changing the CoG of the aircraft , or is their any suggestions on how I can fix this.
Thanks in advance
