Hi Orson,
There is a lot of information here about the treatments available for erectile dysfunction. You can read about them in the treatments database located here. Depending on the cause of your ED, you could make some lifestyle changes that might help. Also if the medications you are taking are not working, there many be alternatives to the particular medication you've been prescribed. You can read about those here.
Hopefully you will find something here that will help. Please stay in touch and let us know how you are doing!Vicki M
