Looking for Mr. Goodbar by Judith Rossner

Theresa was a quietly satisfied young teacher by day. But when the sun went down, her life was an endless, faceless whirl of bars and beds and men she'd never seen before and wouldn't see again. If she couldn't find love, she took chances on men who were better than no men at all. And learned, with each new night and each new nightmare, that finding her man was only the beginning.
