How do you avoid actually throwing up?

I’m 8w4d and I’ve only puked once (actually it was a week ago!) and I really really really hate throwing up. I wouldn’t say I have emetophobia but close. Today my stomach feels really sour like I might actually puke. I managed to kind of stave it off with a little ginger ale but it’s back. Any tips?

Haven’t eaten today, gonna try to do that soon but I have no appetite to speak of.
