Should you consult a physician on the causes of erection failures, alcohol is probably one of the first factors that will be mentioned. I have heard people talking about how their libido or sex urge spiked after taking a couple of glasses of an alcoholic beverage. Yes, that may be true but science has proven time and again that too much of alcohol is detrimental to health in general.
It is not uncommon to see men making “a pig” of themselves due to drunkenness. Drinking too much can have adverse effects on health. Maybe not immediately, but it shows up with time. It is a cumulative process. Oh yes, too much of anything is bad.
