I did about 45 gallons a year for a long time, but then went to 120+ gallons a year in 2012-2014, 86 in 2015, and none so far in 2016. All that high gravity goodness combined with some other lifestyle factors led to major weight gain for me. I've still got about 15 gallons from 2015 for the occasional quaff and for sharing, but until I get myself back on the road to fitness, I'm limiting my intake to five units of alcohol per week (i.e. one bottle of wine or a couple pints of my RIS). Any more, and the scale gives me bad news.
