<p>I have been there. I am also not a coffee drinker and have lived in relatively hot climates and diet colas (Pepsi is my preference) is my drink of choice to rehydrate and get my caffeine.</p>
<p>Colas are bad for bone density and I have issues with that, so I have weaned myself a few times but I always slip back. I never had more than 3 a day, though. Now I am at 1 or 2 a day at most, but ideally I should have none.</p>
<p>I can get going with iced tea for periods of time, but I really like the fizz of the diet colas.</p>
<p>If you don’t have bone density issues, I would not worry about 2 a day at all.</p>
