Dizziness and nausea

I have literally been nauseous since last night I try to throw up but most of the time nothing comes and if it does its just yellow and it's bitter. And I have been getting dizzy too it hasn't been too bad but it makes my nauseous worse.

What could I take for the nausea? I know I ask my Dr. for medicine but the nausea hasn't been that bad except for last night and today.

And what can I do about the dizziness?

Thank you in advance!!! ❤
