Good point! I'd like to add that in case of any doubt, you'd better stop drinking alcohol at least 2 hours before taking any medication. And 3 hours before getting some sleep. Before the party comes to an end.
Because, unlike people are being told by the mainstream media: you won't sleep better on alcohol. Alcohol disrupts REM-sleep, your 'quality sleep'.
Of course, a wiser thing to do would be not to drink any champagne whatsoever at all...
All the best for 2018 to you to!
