The only thing I've found for immediate relief of urinary flow problems is cialis (tadalafil). To lower prolactin Peat has mentioned bromocriptin. I've used cabergoline for this purpose successfully in the past. And of course continue with the progesterone and other Peat approaches. Best wishes.Yes. You´are correct. But my problem is no more prevention. I have a tumor strangling my urinary flow now. I use vitamin A [yolk, liver]. But I cannot find something to alleviate that strangling, even using progesterone 200 mg/day etc, the flow is low. And surgery is a bad option.
