I'm going to get angry and yell at my wife for secretly giving me laxatives
Why did she give you laxatives?
They're disgusting and it makes me feel really bad the next day.
Is your wife trying to hurt you or something? It sounds like you're aware that she's secretly drugging you, so maybe do something about it.
No, of course not! I'm just going to yell at her and scream.
This sounds like an odd situation and I feel as if you two need to sit down and have a chat about it.
