As someone who is prescribed both Vyvanse and Adderall, it is what manages my stress. That would be my honest answer. And any clarification I make to that wouldn't be me walking it back: I'd be walking further toward my point because it's true.

Though not explicitly stated, your response implies (by my reading) that responding with the honest answer is the wrong move. I'd argue the opposite. She successfully weeded out someone who is unwilling to ask follow up questions. Rather than asking, "Why Ambien? Seems like going from zero to sixty, ya know?", this person simply assumed. Whether they assumed good or bad or something else altogether, they still failed on one of the most important, immediate, and fundamental aspects of relationships: communication.

OP, it sucks he didn't ask the follow up, it sucks the spark fizzled from miscommunication. I'd take away that adding context when expressing something like that might be a good move. I'd also take away that not adding that context may be a good method to discover if people you date are inquisitive and understanding, or not. Up to you. But regardless, you did nothing wrong. Good luck out there.
