How to use get_post and “more” ??

Hi,
I had same problem and couldn’t find solution with get_post.
I achieved goal with WP_Query:

$my_query = new WP_Query('page_id=69);
  global $more;
  while ($my_query->have_posts()) : $my_query->the_post();
    $more = 0;
    the_title();
    the_content();
  endwhile;

Seems very heavy but it works.
