My doc gave me samples of Cialis, Levitra and Viagra to try. Viagra seemed to work the best without too much side effect, so that is why I chose it even though the others are supposed to last longer.
From what I can find on the web, the half-life of Viagra is 4 hours. So, if I took a half dose 4 hours after the initial dose, it seems that I would just be replenishing what wore off. Perhaps I'll give that a shot.
skirtchaser - what dosage did you double-up on?
Would still be interested to hear from others who have actually done it.
