I am one who holds her arms out a bit so my drop bars are a bit wider than my shoulders but I have the hoods angled in a bit which works for me although I will admit that when I switched from a hybrid to a road bike, it did feel a bit uneasy, but it was so much fun to ride.... Aerobars on the other hand, definitely felt very unstable at first.

It's amazing how fast your body will adapt if the fit is right. Core exercises for stability may help.
