Hi RachaelMy IBS-D is very similar to yours - often brought on by the panic of no loos nearby or being stuck somewhere I can't get away from easily (like yesterday at the Post Office when the woman behind the counter couldn't figure out how much to charge for the package I was sending....). I would be really interested to hear how you get on with the peppermint oil. I haven't tried it myself but might give it a go.
