Simple. Beer can be found with lower alcohol content, or somethnig flavorful such as a nice smooth stout or a dark lager. (May I suggest Belgian ales or stouts for later drinking and ales and lagers during the day). Switch from mexican to carribbean foods or south american -style foods, which are full of spices and flavorful but not spicy... (i.e. Moe's burrittos could be considered such, without peppers). Honey BBQ wings instead of buffalo, or lots of bleu cheese
and drink decaf or switch to Caff Free pepsi/coke. Or sprite.
You'll be alright man. There are worse things that you could no longer do, like walk.
