[Throwaway account] I run a restaurant for a living. I usually work about 60-80 hours a week and have little time to myself. When I do get time off I like to drink, not to get drunk, but to go out and socialize.  I am originally from Milwaukee and the drinking culture there is not present anywhere I've been since.  

Looking at the last 24 hours, I bought a bottle of whiskey, 750ml of Tullamore Dew, and was casually drinking it on the rocks while at home. 

Here is why I'm getting concerned, the bottle is almost gone and I haven't been drunk since purchasing it. I drank a quarter of the bottle last night, it was over the course of 4 hours and  I felt fine. Tonight after work, drank about the equivalent of half the bottle over the course of 3 hours. 

 the bottle I bought yesterday.

I never get drunk before work or during the day, in fact, I don't like to be drunk. When I drink I try to watch if I've had too much and pace myself off of that. But looking at the amount I can drink, I'm getting concerned. 

To summarize I've finished close to a bottle of whiskey in 24 hours without getting drunk, is this a problem? Food for thought, this entire post was written after drinking half of a 750ml of whiskey.
<bot>: I like to drink, but not get drunk. Is a half a bottle of whiskey a night too much to drink?
