Years ago I'd rarely drink at home, but then drink 2-3 nights out at pubs, parties, etc. Wife and kids later, it's now mostly at home, and rarely out. My biggest issue is I like to drink until I sleep once I start. So I can have 0-2 drinks, as long as I don't start early, but if I start early, even a work night might turn into 6-8, which isn't good for me. Weekends is often 8-10 if at home. Early nights are usually when the wife wants some wine with dinner, which is sometimes just on the weekend, or more often recently 2-3 work nights too, meaning I'm having way too many 6-8 nights each week. I think we are both maxxed out over Christmas/New Years for food and drink, so I think the next few weeks will be pretty quiet, try to let my brews age a little.
My current weekly plan for beer consumption is around 10 long necks a week, and about 3-4 glasses of wine. That's pretty lean for me, but still pretty high for the population, so I hope to stick to that or less most of this year.
