:( can't keep anything down

Hey ladies! I'm open to anything and everything! I'm 8 weeks pregnant and can't seem to stomach anythingggg! Fruits go down well but they come right back up after.. even crackers have been making me feel sick. I'm throwing up so much that I'm losing my voice and my throats feels like it's on fire!!!!! Does anyone have tips for me? Maybe things you were able to stomach or what made you vomit? I do my best to sit up for 1-2 hours after eating anything it's just proven to be unsuccessful my doctor even prescribed that pill that starts with a D that's b6 and that hasn't helped at all. I already took 3 weeks off work because I was feeling so sick 😷 

Please anyone with any advice at all would be verryyyyyyyy much appreciated!
