As I understand it, the halacha is that one should not drink, or drink more than usual, on Purim if it will cause you to neglect any mitzvah.
When you drink a lot or get drunk on purim, has it ever influenced you to miss davening times, daven while drunk, daven without kavanah, derive enjoyment from looking at a woman who isn’t you’re wife, drive while intoxicated (which is of course against the law as well as being inherently dangerous), forget to say a bracha before or after eating, neglect Torah study or shirk your work responsibilities because you’re hungover the next day, etc?
If so, you should have complete clarity and know what you should do: you shouldn’t drink at all, or more than a little.
