If at home and feeling the need for a glass of wine, (or rarely a shot of scotch), it works for me as well... as long as I have no more than 2 glasses of wine or 2 scotches... no problem since I almost always have only one glass of wine, or scotch.

However... when I'm out having a great dinner I'll often drink more than 2 glasses of wine, or scotch. And THEN - I don't sleep well at all. In fact, exactly the opposite, I'm up for most of the night.
