Like others, I've used aero bars for a while. As Will and CC have pointed out it just takes a little time to gain confidence in your skills....stay with it and it will continue to improve. I still come out of the aeros on fast downhills, though. I also do not ride with anyone while using aeros-except for a buddy where we both have our TT bikes and we will go out and do intervals together.

BTW-I now have bar-end shifters on my bars and really like the ability to trim the gears while keeping my hands on the bars. Just another way to add to the riding pleasure!
