Erectile Dysfunction
"I have been using Viagra for about 2 weeks. I previously was taking 5mg Cialis for daily use for about a year. That was great at first but firmness tended to be not as strong at times. My doctor gave me 50mg Viagra samples and my wife and I could tell a big difference! It is more expensive but you could buy the 100mg pills and cut them into halves or even quarters. I am over 50 and have great sex with my wife at least 3 - 4 times weekly. Stay away from the fake stuff. 

I am very thankful to the doctors who made available these medications in my generation! When I think about it, my sex life is greater now then when I was 20!"
