Members confirmed that PAH patients should avoid caffeine rather than carbonation, with many sharing they switched to caffeine-free sodas like Sprite or sparkling water as alternatives. Several members emphasized the hidden dangers of diet sodas, noting that artificial sweeteners can trigger cravings and hinder weight loss, with one member losing 25 pounds after giving up diet soda entirely. A recurring theme was the practical advice to gradually reduce soda consumption to avoid withdrawal headaches, replace it with water or sparkling alternatives like Pellegrino, and recognize that chocolate remains the hardest caffeine source to give up.

Ok all, with the Soda, pop or cola's...the sodium, caffeine, etc. but watch the new sweetners they use, the non-sugar onces have processed sweetners instead which are almost worse than regular sugar. They call it diet coke but it makes you crave more of it, so very little at all or every once in a while, try not to have the daily pop, replace with water like Heather suggested.

Drink water or some fruit juice, I like pineapple. And no caffeine or sodium. I have to give in to a little chocolate on occasion!

I lost 25lbs and one of the biggest parts was giving up diet soda. All the garbage in those drinks was poison for me.

When I stopped drinking my diet colas, I switched to both lime flavored seltzer and Pellegrino sparkling water. I find I really now enjoy both of these as much as I ever enjoyed cola. I also drink a lot of bottle natural spring water...and I admit I drink everything in their plastic bottles which don't help the planet very much...but I do at least recycle the plastic.
