you should drink if you have learned and understand why it is a Mitzvah to drink on Purim, and if you do it l’shaym shamayim.
if you do it because you have been influenced by the velt who have come to think of Purim as a time of hefker and unrestrained kalus rosh, you shouldnt drink.
Purim is one of, and perhaps, THE most Kodesh of the times of the year. the yetzer hara expends much energy on misdirecting us regarding Purim because of this.
