> I don't understand where these long haul truckers find their stamina.
I've spent quite a lot of time driving on I5 in the western US which has a very high volume of truck traffic. I can pretty confidently say that a lot of these truck drivers do not have the stamina you think they have. Many of them are driving just as fatigued and unfocused as you describe yourself being. I make it a point to avoid going over either the south California mountain passes, or the north California ones, after dark, for that very reason.
