How to make myself vomit?

I've had a nasty, absolutely terrible, incredibly awful fucking headache the whole day and literally nothing helped. I tried drinking painkillers, taking a nap and using ice packs but my headache has not only not gotten better, it's actually getting even worse.

Sometimes when I vomit, it usually helps to at least clear the pain a little bit, but for some reason I have a really hard time getting myself to actually do it. I tried sticking my fingers down my throat, using my toothbrush etc. and nothing happened.

Does anyone have any tips or a hack or something to make myself vomit? How do you self-induce vomiting?

P.S. please don't reply saying it's bad to make yourself vomit (I know and I don't care) or to go to the hospital (I got no money bruh).
