Yeah, I went into it the first period thinking "yay, I can stick this in and not worry about changing it in the stall at work" because it can last 12 hours...
Forgetting that my first day is very heavy. I filled one up in about 4 hours (fleurcup). Then checked it again because I was just getting nervous. All in all though, it wasn't so bad to do in the public bathroom. And, I got the "oh shit, I dropped it in the toilet" part out of the way really quickly.
I checked with my Mr and he said that he's fine with me boiling it in a regular pot. He actually stopped me 1/2 way through my question ("so you see babe, these things need to be sanitized between each cycle, which means boiling...). I think I was more skeeved out than him, to be honest.
