You and Barry are married, had been fir a few years now, so you're used to him overworking, whether it be hero work or forensic lab work, you fine ways to get him to stop and take a break regularly do he doesn't run himself into the ground, literally and figuratively in his case.

Barry is currently doing that now working late at the lab ever some chemical he found on patrol, completely losing track of time as he works, then his phone beeps, a text from you, he stopped his work to check what you sent him.

"Hmm? What are you saying now, my love.."
