OP, I just bought the exact same model yesterday. I went from a huge Specialized Globe comfort bike to this so I know where you're coming from. I'd say unless there is something way out of whack with the fit I'd just give it a few more rides until you get use to it. I can tell my bike is sized and setup for me but it's still a new ride and will take a few more rides to get use to the new riding positions. If all else fails I'd follow some of the advice above like getting a stem that puts you in a more upright position, raising the stem (if the spacers allow it) and then possibly a new handlebar that has a bit more of a rise.
