I can not tell you how many times "eat a cracker" was given to me as advice. It used to make me soooo mad! Really? Do you think I'm stupid? Did they really think that eating a cracker, or two, or even twenty, would really stop me from throwing up those 30+ times a day? I wish it was that easy!
This advice was usually given to me by women who tried to sympathize with me, because they threw up, ONCE. :) Bless their hearts, but they obviously had no clue.
Trust me, I have eaten plenty of crackers in my lifetime. I love a good cracker, so I even humored the idea, BUT believe me, no cracker was going to cure this problem! I'm sorry ladies-- and I'm glad if, somehow, that worked for you, but Hyperemesis Gravidarium is not cured by eating a cracker.
