How do I cope with my wife's changes?

My wife has recently started taking steroid medication prescribed by her doctor. A week after she started taking them, she grew a small moustache, started drinking beer for the first time, and took out a subscription to Popular Mechanic. I was very unhappy, but then she somehow fixed the waste disposal unit. Then, when we played in the couples bowling tournament, her point average more than doubled. Should I get her to see a doctor, or leave things as they are?
