'little more than a year here - satisfaction, ev'ry time! although in some 'spontaneous' moments, I've risen to the occasion with no help from Pfizer ;-)
I have been using V for about2 1/2 yrs.I have noticed a substancial drop in effectiveness.I went from 50mg to100mg with no improvement.It may be my age {75} tho I am in good health.Inoticed other posts that mention reducing dosage and I wonder if I am going in the wrong direction.
