Aww, Rachel...feeling you here! This will be okay. Please do take the Flagyl and get better for you AND for your baby. Eat a little meal before you take it, or I just ate crackers with peanut butter and drank some milk. I never had problems with nausea or vomiting. Like Valen said, there were a few loose stools, and the pill tastes crappy. HOWEVER! This is so short-term, and you've gone 30 weeks already - congratulations! Soon you will see your rewards of taking care of yourself and your body, when that little one looks up at you! Awesome!
