Welcome to the community Nicole - so glad to hear that you are working towards your sobriety and getting to the meetings to gain a irl support system. This community is amazing and offers so much support and advice - take some time to read through the threads.
The magnifying glass up top will help you search topics -type in Bartender to see what others have experienced and how they were able to maintain sobriety. It is not easy but it is most definitely possible.
For your shift today - are you able to dip out as soon as its over so you are not temped by the after work shots? Keep this app open and you can type HELP on the Checking in daily to maintain focus #56. This community is active 247 so someone will always be around.
Hope to see you around! Stay strong and a huge congrats on your new found sobriety
