You seem to suggest that this is the first time you have had excessive amounts of alcohol.
Given that you are on medications for anxiety
disorder, I would strongly advise you to quit alcohol because it has the potential to worsen anxiety (especially during the withdrawal phase) and there is a high risk of you getting addicted to alcohol.
Alcohol may relieve your anxiety for brief periods of time, however, in the long run it is bad for your physical and mental health.
I suggest you to talk to your psychiatrist
about alcohol use also, in case you are not able to get over the habit.
