Whiskey and Cola (1 Cocktail)

Replace regular cola with soda water, a zero-sugar cola, or another unsweetened mixer; regular cola is usually the main source of the rapid rise.

Use a smaller measure of whiskey and avoid refills; dilute the drink with plenty of soda water and ice.

Do not drink on an empty stomach. If you choose to eat first, pair it with protein and fat such as a small handful of nuts, cheese, or plain Greek yogurt.

Drink water alongside and after the alcoholic drink, and avoid other sweetened drinks, juice, or dessert that evening.

Check your glucose more often for several hours afterward if you monitor it: alcohol can sometimes lead to a delayed drop, especially if you use insulin or glucose-lowering medication.

If large spikes are frequent, discuss alcohol and medication timing with your clinician; do not adjust insulin or medication solely to cover a drink without individualized advice.
