I just started taking Generic levitra. I am a 43 year old with ED problems and low testosterone. I am glad that I decided to talk to my Doctor. My erection is firmer and I don't have to worry anymore about losing it during intercourse. Experienced being flush and nauseated after I took it and sometimes have a headache the morning after. But with Levitra Generic, my erection feels as good as it did in my 22s.
