This was a great night time snack with no carbs. Unfortunately, a few hours later I began to show symptoms of tetrodotoxin and anhydro poisoning. Yup, stomach cramps, barfing, swollen throat and then some. The next day I couldn't keep down any food and worked with an empty stomach for most of the day. So now I am going to add horseshoe crab on my list of food that I shouldn't eat unless I want to die.
