What would happed if somebody ate a gram of LSD?

I've just read about a lady who snorted 55mg of LSD and survived. Let's say somebody does an experiment and eats a gram while all the time being controlled by medics who try to keep him alive. Would the person trip unimaginably hard or is there some kind of limit? So beyond that limit ingesting more LSD does not make you trip harder?
