Positive Reaction to Cialis = Heart Disease?

What’s the deal with how great I feel at the gym when using Cialis? Anybody know? It’s been so drastic for me that I’ve wondered if I might actually have heart disease. This is because normally during cardio my lungs burn, I gasp for breath, and sometimes my chest even aches.

Always has, ever since I was a kid, but still… When I take Cialis and work out, I get none of the above. I feel like a beast that could do cardio for hours. Anybody else experience this and have any opinions? Do guys who experience a more drastic change like myself have vessels that are in worse shape than the average guy?
