That sounds like a LOT of coconut milk at once, especially for someone who isn't used to it. Do you usually eat a lot of fat? Can you eat a whole avocado at once? How about oily food?
I eat/drink the coconut milk frequently, I feel fine afterwards. But I was living in asia for years so I have had a LOT of exposure to it.
Why do you want to drink so much?
I would suggest you buy the extra virgin coconut oil and put it in your food everyday to reap the most "coconut" benefits.
