Over the counter things to help puking pls halp

I am throwing up AGAIN, I don’t know why. I don’t know if I have a virus or something but I just want relief. What can I get to help nausea and vomiting? What foods should I get? I’m gonna get sprite and saltines but any other remedies?

And no I don’t think I’m pregnant. I have 5 days until my next period and if I was pregnant I don’t think it’d cause puking this early. Also on the pill and it’s taken at the same time everyday.

Also I just had a wisdom tooth pulled on Tuesday so I still have a healing hole in my mouth. I’ve been brushing my teeth, I’m scared to use mouth wash. Can I rinse my mouth with peroxide? I’m sure puking with a hole in my mouth isn’t the best for healing. My doctor is not open today and my dentist IGNORES me when I call to ask questions.

Ps I am seriously miserable and I would appreciate any advice so much that I would hug you in person and I don’t like hugs
