After 3 years used to eating the same meals in France, i.e. Steak and chips
Staying in an apartment this year and bought what I thought was lactose free spread. Had a little with my bread and jam on the first morning and had a reaction by the middle of the afternoon but didn't think much of it
Put it, quite thickly, on my bread last evening and 3 hours later was on and off the toilet for about 2 hours.
Ah well - just bread and jam or extra virgin olive oil and balsamic vinegar for me now
Couldn't you just kick yourself when you get it wrong - even when it's not really your fault?
Done it myself so many times, usually through deliberately flouting the FOD rules - just to see if I can get away with it for once, but often through just not paying enough attention.
Hope you're feeling a bit better by now although I know the aftermath can go on for several days.
Luckily my 'episodes' tend to be a 'flash in the pan' but this one went in for a couple of hours
But I feel 'secure' now thank you
It might be the vegetable oil that is causing the reaction, a lot of vegetable oil is made from highly processed corn oil which causes me problems, I get reactions from mayonnaise too sometimes.
I use Pure at home for everything and full fat mayonnaise is fine, the low fat variety though contains skimmed milk powder.
A lesson learnt
i bet some margarine has buttermilk in it, which is actually worse than butter for lactose.
Don't think there was buttermilk but I'm allergic to any part of milk I think not just the lactose as I can't get on with lactose free milk or cheese at home
bad anxiety with my ibs 
bad days outweighing the good..
Suffering badly with IBS
Bad ibs bout had enough
Still suffering from nausea and pain even though taking metaclopromide.
