Patti, when I made Thanksgiving dinner for my family, I got so exhausted that I barely was able to carve the turkey. When I sat down to dinner I was queasy and exhausted. All I wanted to do was go to bed but I didn't give in to that. I started eating the meal slowly and got my appetite back, along with some energy and ended up having a wonderful evening!
Now, when you don't eat, that will make your stomach upset and you will also feel weak. It's important to eat because you will just make yourself feel worse. Try keeping that in mind the next time this happens to you.
And, in answer to your main question, no, I have never had warnings. Many times it's caused by barometric weather changes, weather being too warm or too cold, or just overdoing things. You do need to pace yourself with this lousy illness.
