On my Breezer, I moved my seat back an inch and it helps. Easy to do.
I, too, want to raise my handlebars up more than I can. I probably should have gotten a large frame instead of medium. I sometimes get pain in my right hand--I think it is because the handlebar is too low for the height of my seat. I'd like to try bar ends that tilt forward, but I'm not going to bother for now.
The bike is still comfy to ride and I enjoy it.
