A Case of Beer

For a Prompt: Sherlock and John go to a beer festival (either as part of a case or just for a day out) and Sherlock's reluctant and crabby at first but then gets swept up in it and eventually wins the Yard of Ale competition and then John has to help a very drunk Sherlock home with a very bloated belly & use his doctors skills to tend to his drunken, bloated flatmate. Belly rubs!
