One of the more common drugs for impotency I have been hearing about is Tadalafil which is intriguing me as I also am suffering from erectile dysfunction but I have only been taking one drug ever since which is Viagra. I did not want to change drugs as I still find it effective for me and I got quite accustomed to using it that I don’t want to change it anymore, but my doctor said I am developing some sort of resistance to it already so I had to alternate it also with some other to avoid that from happening. He gave me some choices actually to either Buy Tadalafil or Buy Levitra, both of which are also known to be proven drugs for erectile dysfunction. Of course first I did some research on these drugs as I know full well what they can do but I want to know which will be more better for me. I went to some sites including www.generic4u.com and read about these drugs too. It is said that Levitra or Vardenafil is more newer and in fact this was better and more faster acting than the others but tadalafil is also effective and more synonymous with Viagra which I am currently taking so I am having a hard time choosing between them actually. In the end I chose Levitra as anyway, I wanted to see how better it is than Viagra and I hope I don’t get disappointed.
