Never tried Levitra, but have used a fair amount of Cialis. Cialis gives me headaches and makes my sinuses fire up, but I swear it's the best recreational drug ever made. It takes very little C for me to get the desired effects.
I'll try Levitra and vitamin V to see if they have similar efficacy to C without the sides, but the 36 hour window is a significant bonus of C in my opinion. I'll reply back when I can offer first-hand info.
