Curious; what are the perils of drinking wine with dinner?

Alcohol relaxes the muscles and tissues in your airway and causes more obstruction. People who normally do not snore at all will often snore after drinking alcohol. If you already have a problem with snoring or apnea, it will become worse after drinking.

Drinking alcohol prior to sleep can cause poor sleep quality.

So I should day drink instead?

[robodale]

I am pretty sure you know the answer to that.

(it is "yes")

[jacobyoder]

that's still 'before sleep', isn't it?

[robryan]

In the morning is optimal in terms of improving sleep. The alcohol will be largely out of your system before you sleep.

Unrelated to CPAP, but alcohol is a strong suppressor of REM sleep (cf. Walker, Why We Sleep).
