No. I quite like seltzers - whether plain or with a hint of fruit flavoring, but with no real or artificial sweeteners.
Like me, you enjoy a Diet Coke every once in a great while but the hit of caffeine can be so overwhelming that you don't revisit the experience for months.
If you're talking about very hot weather, like over 105°F/40.5°C, then yes. I can tolerate lower temps when the humidity is very low (as in So California).
