Throwing up 17 hrs straight (5weeks)

I am 5 weeks pregnant and I just found out yesterday. The day before yesterday I had 1 mule (alcoholic drink) not thinking I was pregnant at all as we were waiting to start ivf but anyway yesterday I was throwing up so bad all day to the point where I had to go get an IV and Zofran well this morning I still feel a bit nauseous and needed to take more zofran did anyone have this as a symtom? Or do you thinks it’s from having that 1 drink? It’s scaring me a bit for several reasons as I just want to make sure my pregnancy is a full healthy one but how can I do that when I’m throwing up the lining of my stomach 🥺 I also don’t want to be miserable this whole pregnancy
