Excessive binge drinking is something that needs to be taken into account if you are choosing to take medications for an anxiety disorder or any other thing. Some medications also carry a risk of other side effects like memory impairment which is another big reason why the next day you might be feeling a little bit of regret If you can't really figure out what actually happened and then of course there's the most serious things like organ damage and ulcers especially if you're taking kidney or liver medication as well so if you do feel anxious the morning after it's important to recognize and understand why that might be the case before you kind of panic.
