thanks for the insight. Its now two days removed and i still feel crummy. I tried to eat a begal and felt very nauseous. I wonder if maybe i do have a bug
Yes, it can still be in your stomach for 3 hours after, it takes longer than that for it to leave that area.
You could have had a flu bug, I do not know of food poisoning from frozen lasagna.
If you have the flu, then yes, it is normal to feel bad the next morning.
Hope you feel better soon.
