Hello and welcome to the Anxiety Community!
Alcohol absolutely positively triggers anxiety in a LOT of people, especially ones who are already prone to it. Usually, a person will have a spike in anxiety the days following indulgence with alcohol, and obviously, the more you drink, the worse the anxiety seems to be.
If you search the forum, you will find a lot of topics about this. There is one long and old thread though, that I think will give you a lot of insight into this issue.
