1) psych: Prozac. Why is it good? a) a little goes a long way - I am on 10 mg and it is enough b) everything it does is good c) there are no side effects

2) non-psych: Tazorac cream. Why is it good? It makes the skin especially good, reversing some sun damage and preventing breakouts. No side effects, either. The only bad thing about it: the price. But again a little goes a long way.
