My HG is back and with a vengeance!

I thought it wasn't going to be so bad this time since I didn't start vomiting at 5/6 weeks like I usually do. Well last night it went big. I threw up everything including stomach acid. I am 8 weeks on Wednesday. The pills my Dr prescribed to help are no long affective since I throw them up shortly after taking them. I can no longer stand up for more than a couple mins because I'm so week. I'm calling my obgyn in a couple hours. I hope I'm not hospitalized and that maybe they can give me a shot or something. With the holidays coming up I was hoping it could wait so my family didn't have to deal. Hypermesis Gravidurum sucks so bad. I'd rather have the flu.
