Expert working on male erectile dysfunction has come to the conclusion that Levitra is a powerful drug to overcome erectile dysfunction. The expert Samuel Ward also recommends this drug to males who like some drinking and heavy eating with the drug. These users feel that without eating and drinking they cannot come into the mood. Mr. Samuel Ward says that this drug is as effective as Viagra and provides the same duration of 4-5 hours. It starts its action after at least half an hour of being swallowed in. 20mg Levitra is a higher dose of erectile issues, which are not overcome by the lower doses.
