It sounds to me you're just hesitant to accept your hair's natural volume. I too have a lot of hair, and even if I come across a frizz-free day, it's still voluminous.
If the volume really bothers you, then try half-up half-down styles or go with a stronger gel/heavier product to weigh the hair down. (Granted, the second suggestion has never worked on my hair, but give it a try.)
