Doxylamine / pyridoxine
"I cannot keep water down, let alone food, if I don't take this. I was hoping it would end after the first trimester and I could stop using it daily, but I'm 4.5 months and I still can't be without it. So grateful it's class A because I don't know how I'd work and function without it. Wishing I didn't need anything! Also, I should add...I only take half the dose: one at night and one in the morning. Two during the day is way too much; you'll feel drowsy and sedated. I learned that day one and realized I don't even need that much to alleviate the symptoms."
