The prescription made me do it

Caller: I want to sue a drug manufacturer
Me: Why?
Caller: I was on this drug and it destroyed my marriage.
Me: I’m sorry...what now?
Caller: My doctor warned me that this drug could put me into a state where I wouldn’t know what I was doing.
Me: And this destroyed your marriage how exactly?
Caller: I got into my car, drove somewhere, met some guy, checked into a hotel and cheated on my husband while I was using this drug.
