erectile dysfunction
"Started on the 10mg as needed about 3 years ago and the results are impressive. At 63, it was getting more and more difficult to become and stay erect and wasn't lasting. The 20mg had me walking around with a full erection without any stimulation like being a teenager, but had headaches and stomach upset. Less side effects with 10mg and almost none when using them cut in half. The 5mg are still plenty effective for at least a day and a half. Cutting the 10mg in half gets the price down, but still pretty expensive. However, I wouldn't want to be without it now."
