Sickness

I understand at 6 weeks your gonna have "morning sickness" but is anyone else having it CONSTANTLY the whole day I usually actually get sick btwn 2/2:30p but other then that I stay nacious feeling like I want to literally ALL DAY, I've tried peppermint tea, candies, ginger ale, lemon ice, Emetrol, nothing has helped but btwn this feeling and constant tiredness I'm so over this all ready and we have a long way to go... I was expecting it but I never would have thought it would be this awful. I have my first appointment & ultrasound tmrw I'm praying there is only one baby in there because my sister never had it this bad and my aunt or sister in law eaither. As much as I don't want to take medication I'm seriously considering asking for the Zofran. Any suggestions??! TIA
