I have been on Flowmax almost a year. It solved the hard to go problem almost immediately. I do not have any problem going to the bathroom and usually make it through the night now without having to get up. I do not have a particularly hard time getting an erection, but I have notice a much lower ejaculation and less satisfying climax. But age could also be a factor for me at 64. For the most part I like what Flowmax did for me. Before the doc put me on Flowmax there would be times I had a hard time urinating and it was scary. For me I will have to continue using the drug.
