Before I started taking Amlodipine my mojo was great. I have to use Viagra and my wife hates it because it turns me into an animal as I have to go round after round in order to quench the sexual appetite. My sex drive has gone down and its hard to get an erection without taking Viagra. Cialis was great in that its effects lasted longer than Viagra but I did not get as hard with Cialis. Viagra did it. I don't like having to drop $74 each week for a pack of 6 pills. Please help.
