I'm sure others will answer this, Steve, but it tested better on women, and they don't know why. However they're now retesting men in the UK. And a few months ago someone posted a glowing report from a man that was on it a year. There are other drugs that will follow like Cilansetron(I don't know how soon, though) that seems to do well for both. Flux mentioned something beginning with R the other day I never even heard of..Flux?
