Wish it was just MORNING sickness!!

I could be anywhere from 7.5 weeks -9.5 weeks. I have irregular periods so I'm not sure how far along I am and I don't have my first apt till November 3rd. AnywAys

This "morning" sickness is horrible. It last all day 24/7. 90% what I eat comes right back up. I work 12-13 hrs shifts and it sucks rushing to the bathroom to vomit. I don't have an appetite and I basically have to force myself to eat . I've done saltines , popsicles, gingerale, pedialite , nothing is helping me get relief. Any ideas please!!! My body feels so weak and tired and I know that's normal but I'm struggling lol
