Cialis has changed my life. Started getting problems with ED two years ago. Doc put me on Cialis 1 year ago; 10mg to start then 5mg then 2.5mg daily. On first night with 10mg my wife was amazed and she was amazed in the morning then a noon. 3 times in 14 hours! Any sort of sex is now possible with her. Cost is high but I found Tadalafil generic works just a good. No side affects for me, just wood.
