Vodka (1 Fl Oz (No Ice)) and Sugar Free Energy Drink (Red Bull) (1 Serving)

Avoid combining vodka with sugar-free energy drinks: caffeine can mask intoxication, raise stress hormones, and make glucose responses less predictable.

Choose a non-caffeinated, unsweetened mixer instead, such as sparkling water with lime, and limit or skip alcohol if you notice repeated spikes.

Do not drink on an empty stomach; if you drink, have a balanced meal first with protein, unsaturated fat, and high-fiber vegetables such as leafy greens, broccoli, peppers, or mushrooms.

Keep the alcohol amount small, drink slowly, and alternate each alcoholic drink with water; avoid additional caffeine before or during drinking.

Check your glucose before drinking, several hours afterward, and overnight if you use insulin or glucose-lowering medication, since alcohol can also cause delayed low glucose.

Discuss recurrent spikes or any readings that remain unusually high with your clinician, especially if you have diabetes, take glucose-lowering medicines, or develop vomiting, confusion, severe thirst, or rapid breathing.
