..."[0019] The engorgement of the invention is typically for a "cumulative prolonged" period, as described further below. The engorgement period is thus usually at least 3 hours, but may be 31/2 hours, 4 hours, 41/2 hours, 5 hours, 51/2 hours, even up to 6 hours, but heavy engorgement of a penis, say 40% or more, is usually avoided for extended periods of time, i.e., of more than 6 hours. The erectile response may, thus, be of the 3-6 hours engorgement resulting from a single administration per 24 hours or as a result of a plurality of administrations in this 24 hours period."
So I wonder if it the cumulative time could be broken up into a morning and evening session of 2 to 3 hours each session.
