Around 7 weeks the morning sickness hit me and it hit hard. I lost over ten pounds in a week. My doctor gave me Unisom to take at night to help sleep through the night and maybe not have to throw up as soon as I wake up. Then a B-6 vitamin to help the nauseous feeling during the day. It helped. I am now 12 w 3 days and today has sucked. Throwing up every hour or so. I don't know what's happening. My medicine isn't helping at all. I'm miserable.
