Completely feel the same on that, but it can be up and down.
I got so bad that I felt I had to drink to even be sociable at work and get through the day.
As for going out socially, I often go to see bands and this is often on my own and the problem with that is that if you have to hang around a while to wait for bands, it's so much easier to hang around and drink pints, which in turn made me more sociable.
BUT in hindsight, the amount of bands i've seen who I remember nothing of is shocking.
