Is it normal to feel a bit sick, when you feel tired?

Question

I've noticed, when I feel tired, I start to feel sick, as well. I heard once, that feeling tired, and sick, as well, are related. Is this true?

Answer 1

Yap it's very normal. When I am really tired, that's when I tend to feel sick the most cos you get the headache which makes it even worse.

If you're just plain tired (not over exerted) then chances aren't you won't feel too bad sick wise, but when you're over exerted and really tired that's when you start feeling sick.

Answer 2

not normal. probably something else.
