too much of a good thing

Beneficial becomes harmful

Something desirable becomes harmful or unpleasant when taken to excess.

The phrase acknowledges that even positive things have limits: Chocolate is wonderful, but a whole cake is too much of a good thing.

Often used to justify moderation or explain why an appealing situation turned sour: I loved working from home at first, but after two years it became too much of a good thing.
