Now I am supposed to take 3 tablets like you wrote in this e-mail. But I discovered that I had problem sleeping because it acted on the nervous system. Please don’t take 3 pills at the same time. It will raise your BP suddenly and your heart start raceing fast. I know one guy who end up in the emergency. Fred, it may be more effective to me since I still have morning erections and doctor told me there is nothing wrong with you and it is only in your head. Every one is different as far as the effect of any medication is concerned. My doctor also gave me some free samples of Viagra from nfsno.org Canadian online pharmacy and said it will build your confidence and you will be alright.
