Sounds like me. I'm working on it by making my rides more intense rather than cruising. Instead of shifting down to the bottom gear when I get to a long hill, I limit myself to 2nd-bottom and see how I go. I've surprised myself - got up both of the bad hills on my commute without downshifting. So I will do it again in one higher gear, etc.
I am also, on the advice of my trainer, taking a long steady climb on the morning ride in the highest gear I can manage.
So far working well -shaved 10 minutes off my commute time.
