One thing to remember, if you are getting through 10-12 beers on a Friday and Saturday night, then no doubt you are technically over the limit to drive on Saturday and Monday, which is a thing a lot of people do not consider, if you just feel “rough” on a monday morning, you probably shouldn’t be driving.
I replaced quantity with quality, trying to seek out interesting and really tasty beers and as you say above, just sipping them and making 1 or 2 last an evening.
Helps also if you have your bike kit laid out where you can see it and an alarm set for 6am to get out on the bike, less likely then to tuck into a large quantity of beer?
