Blackout by Erin Flanagan

Maris is freshly sober — seven months in, after a much-alluded-to rock bottom moment. She’s white-knuckling through wanting a glass of wine at all the usual points in her day, but grateful to no longer wake up with a fuzzy half-recollection of the night before. Her family, a daughter and a relatively new husband, haven’t directly addressed said sobriety, but everyone seems to be functioning well. And then, Maris has a blackout… but she’s still sober.
