You also may have been experiencing "induction flu" ... The only time I got nauseous from fat was when I ate too much coconut oil in one sitting. oops. Tummy did NOT like that much all at once.

And THAT might be your problem.

Also, do you still have your gallbladder? If not, that could be part of the problem. Although mine's long gone, it's been long enough that I don't have a problem with all that fat.
