Absinthe and
witch's brew both count as alcohol as they say "potency" on the page, meaning that potency level 1 gets you drunker by one level. Level 5 potency like
aged dwarven ale gets you drunker by five levels (which is max). The most efficient way of going for drunkard is to sit in front of your computer screen and click on a new ale every minute for 1000 or 10,000 minutes. Since that isn't going to happen and it is illegal to use a third party program to do it for you, you should break it down into manageable sizes, I do about 30 minutes at a time before I get to bored. There used to be a glitch where you could do this in a MUCH shorter amount of time, but I don't know if that has been fixed. But what you did was get to level five drunk, zone to your guild hall after about twenty seconds, wait twenty seconds, and zone back and you would get three minutes to your drunkard title. That cut the time down by a third, but is 66% more expensive on an already expensive title (minimum 2,000,400 gold title if you use a bot to drink the ale for you for 10,000 minutes straight).
