Hi, I have gone through your question. I am practicing anaesthesiologist and pain consultant. First I would like to know that, you are a diagnosed patient of erectile dysfunction or you think you are having erectile dysfunction? Because most of the time erectile dysfunction is just psychological and don t require any treatment other than councelling. If you are already diagnosed as having erectile dysfunction then better you consult physician for appropriate treatment. About night fall, its not a disease as such. It is just involuntary ejaculation of semen during sleep, especially in early morning. It doesn t require treatment. As being allopathy doctor I cant tell you about lycopodium, but as per my knowledge its for stomach upset, which is normally associated with erectile dysfunction. So don t take any medication without doctors advise
