I had a few of these situations early on JHE, work related stuff which I couldn't get out off and where there would be plenty of alcohol. I dealt with it by being a hyperactive host, making sure everyone else had a drink in front of them. People are more likely to notice that you're not drinking if they're looking for their own next drink. And plus lots of rushing around does help to burn off any nervous energy. I hope you have a good night x Stay strong x
