Interaction between anxiety meds and alcohol.

I am currently on anxiety meds, specifically sertraline, flupenthixol, amicon and clonazepam for SOS. And sometimes melotonin for night. most of my meds are prescribed at night. Except a sertraline which is taken in afternoon. Every Weeknd at the party after drinking booze, it becomes difficult situation. Weather to take meds or not. And I had few questions about it:-

1) is there any interaction between sertraline, flupenthixol, amicon and clonazepam and alcohol

2) if yes what the interaction causes

3) after how much time we should take booze after having meds

4) does after taking meds with booze causes relapse in medical treatment of psychiatry or causes anxiety after the meds or alcohol effects wear off.

Google is showing mixed answers, I want an expert opinion. Please reply
