You have not mentioned detailed symptoms, but as the symptoms had resolved on medications in the past, and there is a recurrence of symptoms, I suggest that you consult your psychiatrist again, and take the medical opinion, and start treatment as per advice.
Apart from medications, CBT (cognitive behavioural therapy) would also be beneficial and must be added. As for alcohol, medications or no medications, alcohol needs to be avoided by all people, and for you, alcohol increases anxiety symptoms so total abstinence is advised.
