I don't know if it's just me, but the first time i tried cilais the effects were amazing, wood for almost 3 days straight. But the second time i noticed almost nothing, and i even took a second tab a few hours after the first and still nothing. I tried it again a few days later and once again, nothing. They were the blue triangles BTW. Anyone else not feel any extra effect after taking cialis? Maybe i'm just a non-responder...
