I haven't found anything so I take 10 mg of cialis every other day or so. at almost 70 years of age, my sex drive is pretty low most of the time, but I get an erection if stimulated. in fact, once I get to a certain point, it's almost instantly hard, there is no stopping it.
the best things to do are eat right, exercise, don't smoke. don't overdo booze and/or drugs.
