In 2000 I was flying Swiss Air and there was a lot of turbulence. I asked for a G and T to calm the nerves and the hostess could see I was really nervous. She came back with the drink and a small white pill and said it would calm my nerves. I took it without question and can't believe I didn't ask what it was. With the alcohol, it worked and I was much calmer.
I've always wondered what it was. Any idea what an airline could give out back then that would calm the nerves? It really surprises me now that they could do this.
