text: i am not able to get a full erection all the time? is there anyway i can arouse myself better? i went to the doctor and told him the same thing---he gave me a sample pack of lavitra----wow---did it work or what. i got an erection that lasted and was fuller than normal. even after i blu, it stayed up. after a while my wife said ok i'm done.  consult your doctor about this and read the warnings on the label--- some of the side effects that i did encounter was a stuffy nose, headache, and  very mild dizziness.
