I ve been diagnosed with BPH, was prescribed Alfoo 10mg but my nocturia and frequent urination continued unabated. It was very difficult to get a good night sleep. One herbalist prescribed me prostonil 320mg (saw palmetto 320mg standardized extract, 85-95% fatty acids) which I ve been taking over the past three months. Symptoms are at a low now, so my question is shall I stop taking it? Or shall I take it once daily like I took Alfoo 10mg throughout my life?
