How do people work with this nausea???

I’m 7 weeks tomorrow and my nausea the last few days have been a nightmare. I can hardly work and resorted to telling my manager and closest coworker bc my work is slacking. Thankfully, they’ve been very understanding. I have no idea how I’m going to survive the first trimester while working if the nausea gets any worse. How do people do this?? I’m trying not to call out too many times and use too much of my PTO
