I am lucky to remember to take the a few days in a row. And I have an alarm set. (I can't keep mine down until afternoon, and I'm normally busy trying to get things done as soon as I am able to stop the vomiting)
You'll be fine!! I couldn't take them until I was 22 weeks because they made me nauseous! My ob said just take them when I was able. You and the baby will be just fine don't stress momma!
