[Grammar] "I have started" or "I started"

[asphyxia]

Hello.
I have a question. Which is correct in this sentence:

"I have started eating raw fish and I think I'll die soon" or I started without "have" is enough? What is a difference?

Piscean, I think you mean 'at some earlier time'.

 

[Matthew Wai]

I think Piscean means 'at some later time after starting eating raw fish', but I am not a teacher.

 

[Matthew Wai]

I think Rover_KE means 'stopped eating it at some earlier time before now', but I am not a teacher.
