The product name brings back bad memories.
There was a product called Fizzies when I was a kid. It was a tablet that would flavor and carbonate a glass of water. Apparently they were too expensive for my mother’s taste so I only had them at other kids houses.
When I had a stomach ache as a kid, my father would inevitably ask me if I needed a physic. I think that was code for enema or laxative. I tried to keep my stomach aches secret because of that. He thought it was funny. I thought it sounded scary.
