Well, I don't know if alcohol makes me more productive...but I do think a small amount actually HELPS me focus on tasks.
Why is this?? I am not sure! Maybe it just relaxes me enough to get stuck into them, or it quiets my brain a little, so I'm able to focus better.
Of course, I wouldn't say this works for everyone
I also find that other medications (such as cold drugs, and codeine) have the same effect...
I sometimes suspect I'm a little ADD or something, because I really find it difficult to sit down and focus on one task. It was purely by coincidence that I learned that cold medications helped me focus, as after taking one for cold symptoms I was able to sit down and actually work for hours without having to force myself!
Now, I'm not trying to say these things are good necessarily, but sometimes if something helps then it isn't perhaps such a bad thing either!!
I don't regularly drink to excess, and I've also gone months at a time without drinking. It would be nice to say I've noticed a difference between the times I've had a few drinks a week, and those times when I've had none, but honestly I've never noticed!
