A friend of mine takes proscar, which is the identical chemical to propecia. He's been taking it for years and is 55 years old. He loves men like you love women. His libido appears to be untouched by any adverse side effects from the medication. As you noted, everyone's different. No argument there. But before going cold turkey, you might first experiment with taking LESS propecia. Maybe a dose every other day, or every third day will help you keep the hair you've regrown and allow your sex drive to ramp up again.
