... my libido from the begining which bothered me. From three month ago, I begin to use nicotine patches to give up smoke and from then, I found annoying impotence too, now I cannot make intercoarse and have difficult coituses. Another point is that I suffered a very severe lung disease few months ago, ARDS was the case in fact. Please help me, what is the cause and what shall I do to get rid of it ?
