Last weekend, I was at a restaurant and ordered a salad.  I used oil and
vinegar.  I added generous amounts of oil to the salad.  Within about 4 hours
I had severe cramping.  The pain lasted well over an hour.  Has anyone else
experienced this?  Should I use any particular kind of oil?

Thanks,
Gerry
