My coach gave me a recipe list of different "virgin" drinks to make if I ever felt like I wanted to "drink" with friends (luckily, I hate alcohol so only drink like twice a year, and the occ beer at dinner). So, I'm used to feeling left out and I'm ok with it. The "virgin" drinks consisted of club soda or IP packets with extracts or lemon/lime juice. You could try making mock cocktails if you want to mimic having a drink
