Gray,
Take a look at this old thread discussing 5mg vs 10 or 20mg Cialis.
www.healingwell.com/community/default.aspx?f=35&m=1655954As you will see, 5mg is just for daily blood flow -- it will not havemuch effect on post RALP patients and certainly not enough for intercourse.
That you are getting almost good results from 5mg says you will probably have full liftoff with 20mg. Just at a little extra cost.
