How many drinks a night are considered safe and why?

It all depends on how much u eat before u start drinking because drinking is not safe at all unless u have something on your stomach to back of the alcohol whille you feeling the buzz. I more u know how much you gonna drink the more u should know how much u gonna eat to back it up. Cuz if not the dangers it can cause can be stomach bleeding witch u will have black stools all the time everytime u have to go. Liver damge , brain damage.
