Feeling super unwell when tired

Tämon

Does it ever happen to you that you start feeling incredibly unwell even sickish when you stay up late or later than usual? It makes going out quite of a pain, literaly speaking. Also when I stay up super late, my intestines start acting up and I get diarrhea 🤷 I happends regardless if I am having a normal dinner (some bread with cheese/ham/jam), if I am eating outside, and even if I am not having dinner at all.
