But be mindful what you are asking for. Some drinks are beautifully balanced and delightful in their right proportions, so messing with that is rather sad. If you are just having straight up vodka soda or something then go for it.

This is the right answer - cocktails are made to a recipe, if you want more booze just have 2. Of you want a stronger drink just have straight up spirits and order a double.
