I know viagra has progressive dosages, but I've switched to cialis since the window of opportunity is longer and the headaches are less.  Anyone have experience doubling the dosage?  I do need one dose to get a stiff enough erection for intercourse, but I'm wondering if my chances at a second round would be enhanced by doubling up.

I think your asking the wrong people, you need to check with your doctor...There are many medical things you have check before assuming a double dose will give you a double pop...

I have also used Cialis, and I have not found it more effective than Viagra--quite the contrary.  As to doubling the dose, I did try doubling the dose with Viagra (against doctor's orders) and did not find it more effective.

But I need the drugs to get an erection at all.   I find that I can get another erection with the regular dose of Viagra with enough time and attention.   I don't think doubling the dose is a good idea.

Suggest not even thinking about a double dose.

that is a triple dose, basic is 10mg

I recommend not seeking advice here from the snake oil charmers and pill poppers.

Seek the advice of a doctor for these matters.

WTF

I do find that medical professionals err on the conservative side on advice.  I was looking to see if any adventurers had tried increasing dosage above  the officially recommended maximum.  I have 20 mg pills through my prescription, so I'll stick with those.
