I have been craving pulled pork sandwiches for about a week now. I just finally broke down, bought a crock pot and made it for the first time ever... less than 15 minutes later I'm in the bathroom dry heaving but not actually getting sick... now i keep constantly feeling like it wants to come up and having to go to bathroom just in case... why Is it always the craving I'm wanting most that makes me sick... with my first it was pizza... with my second it was eggs
