Low calorie tit’s mixer with no aspartame?

Hey everyone. I’m going on vacation next week and looking for a low calorie mixer that doesn’t have aspartame. Any ideas? I LOVE vodka and pineapple juice or vodka lemonade but don’t want a 200+ calorie drink. Unfortunately, aspartame triggers my migraines so I try to avoid it which crosses off about 90% of diet drinks off the list.
