Hi Purbita, I'm not a doctor, but from how you explained it, I think you are Dolphin chronotype based on the categorization of Dr. Breus. And I am a Wolf. There are unique things that help dolphins. You can take a quiz at the below link to see if that makes sense. Let me know if I'm completely wrong. 😅
