Over the course of six hours, I had four gin and tonics – not enough to be drunk. I’d been sitting in the park with my sister and had been to the bathroom once in that time. When we got up to leave, I went from needing to pee a bit, to needing to pee so badly that I couldn’t stop it. I’m so embarrassed and upset about it because I don’t know why it happened and I’m terrified it could happen again.
