First trimester morning sickness

It’s awful I’m contemplating calling out of work because it’s getting that bad and making me miserable. I work 12 hr shifts and the nausea comes and goes. I battle it by eating crackers and drinking water, and occasionally eating sour fruit/candy. However I’m just tired of pretending like I’m ok when I’m going into patients rooms and talking to them but I feel like I’m about to vomit.

Idk how I’m gonna last through the first trimester while working, thankfully the nausea subsided the later in the night it gets but before then I’m struggling😭any advice on how to erase the nausea?
