I think the last time I mixed beer and hard liquor was around 1989.
For me now, it's one or the other. I can't mix'em.
And now I stick to only one type or brand per sitting.
The last time I had multiple varities as in 4-6 different kinds of drinks, was around 1980.
No way in hell I can try that now.
I have a friend who still drinks wine, different brands of beer, shots, mixed drinks all in the same night. That would rough me.
