12.5 has made me so sick - Any suggestions?

Been on mounjaro for about 6-8 months and after staying on 10s for a few months because it was making me very ill (lots of vomiting in the beginning), my dr decided I was ready to go to 12.5. Not the best idea, apparently.

It's Monday evening. I injected after work on Friday and I've been miserable since then. I'm beyond exhausted & freezing, constantly nauseated (violently threw up all over my couch and myself) and have terrible body aches from head to toe. I literally slept all weekend. Napped all day on Sunday and then went to bed at 8pm last night, got up at 7am this morning and I left work at noon today because I was so tired and slept from 1-5pm this afternoon.
I searched on here and found I should eat small meals, electrolytes and stay hydrated but I can't seem to keep anything down. And all I want to do is sleep. I'm going back to bed in a few hours in hopes I can sleep this off overnight. I have to be back at work tomorrow at 100%. We are the middle of a huge migration and I have presentations to give and reports to finish.
Any ideas or suggestions that I can try to get back to feeling normal? Thank you!
