Shower beer/seltzer/soda is great at the end of a long day/hard run/big trip etc from the hot water getting your body clean, and the cold refreshing beverage you drink during the process
If beer #7 gets brought into the shower at 3pm, you likely need to sit down and take a look at your life choices
I don't even drink that much anymore since I mostly just have edibles, but on occasion I will take a drink with me into the shower after a long day, should try it.
