Second: my guess would be likely you are lactose intolerant and how the shrimp is prepared is important.
Some sauces have milk products and with addition of additional cream sets you over the edge.
So if there is time that passes you are dealing with only one serving of dairy product.
Thats my guess anyway.
Remember I am not a doctor nor do I play one on TV.
Like I said, I never eat them together, and avoid eating them within 4 or 5 hours of each other. Last night was an exception, so I will start extending that time allowance.
It doesn’t really matter how it’s prepared (fried, broiled boiled or grilled), but I know I never should eat shrimp, crawdads, lobster or crab (there are others), within several hours of consuming anything dairy, or vice versa.
