I'm pretty sure it was from my very large calcium pill. I have been taking them for several months, and this is the first time that happened to me. I chugged a ton of water as fast as I could to rinse the remaining powder down into my stomach, where it belonged. I blew my nose to get the calcium stuff out of there.
There was no repeat of the above incident, but it took me several hours to regain my ladylike composure. I feel like I can identify with dragons better now. Except while they breathe out fire, I breathe out vitamins.
