Withdrawal or hangover??

I’ve been drinking 2-4 standard drinks a day the past week, so not a crazy amount, but for the past several days I’ve woken up with a headache and drinking has made it go away. But the headache is getting worse and not going away and I’m not sure whether drinking more will help??

I took Advil 30 mins ago, which ALWAYS cures my headaches, but it’s not working so I’m confused/concerned. Would it be dangerous for me to drink some more (like 1-2) after Advil?
