Hi, I--apparently--made the bone-headed manuever of using some rancid cooking oil while making some waffles this morning. All day I have had the taste leftover in my mouth, and my stomach has been a little disturbed. No vomiting or otherwise, just a queasy feeling. It was too early for me to notice the bad smell, and I didn't know that oil went bad....That bad anyway! Is there anything I should do? I tossed the oil and will smell any oil before using it in the future. Should I expect worse, or after ten hours am I safe to assume the worst is over? Thanks for any help.
