Very difficult to have a good night's sleep if you have alcohol in the proximity of bedtime or even if you have two or three drinks several hours removed from bedtime. It still will linger, and it'll manifest itself in a number of ways, but probably most notably is kind of a reduction in the quality of sleep. So, you'll trade more deep sleep and REM sleep for light sleep. And then, the other thing you'll see is much more frequent wake-ups.
