Unifying Contradiction

I couldn't sleep last night, so I went looking for a nightcap to help. I had planned to have a brown cow, but it turned out we were almost out of cream, so I did without a drink. Today, we have wine, and I'm now on my fourth glass. It seems to be working, because I'm getting quite sleepy. Although my coordination is going, I still seem to be able to touch type at a reasonable rate though...
