Sure why not? People will say DO NOT DO IT because of yeast and Sugar but the truth is,if you enjoy a beer the ENJOY a beer! Apple cider vinegar(raw with mother) is a fantastic natural drink and it is all about balance so yes by all means sink a few cold ones,and sink some ACV before bed and i bet you feel fine in the morning(unless of course you drank too many cold ones lol)
If you cut out too many things you enjoy in life you get MISERABLE.Balance is they key,YING and YANG my friend,yin and yang! Enjoy your beer and plug your ears when the uproar of forum dwellers shout at you for enjoying them! Peace.
