I am doing a 50/50 hydrogen peroxide and water douche. to relieve discharge and odor but it is not working that well. what else can i do?

That is too strong: That may be too strong to perform on a prolonged basis. It is first important to figure out why you are doing that. You may benefit from an examination, cultures and antibiotics or antivirals or antimycotoc agents. On occasion a betadine douche may help but this should only be used for brief periods and not sustained therapy.
