Single sticky within multiple loop

Hi folks,

I’m trying to work out a solution so that, within a multiple loop that displays 1) a sticky, 2) a list of posts, 3) a second list of posts, only one sticky shows though more than one may be defined.

This is my current code:

$myposts = new WP_Query('posts_per_page=8');
  while ($myposts->have_posts()) : $myposts->the_post();
  $do_not_duplicate[] = $post->ID?>
<?php if ( is_sticky() ) :  ?>
//sticky stuff
<?php else : ?>
//first list of 7 posts
<?php endif; ?>
<?php endwhile; ?>
<?php query_posts(array('post__not_in'=>$do_not_duplicate));
 if (have_posts()) : while (have_posts()) : the_post();
 ?>
//second list of posts

I just saw @alchymyth code in this great post, which gets me close, but I can’t seem to work it out so that I both limit the number of stickies AND get my other posts to display without duplicates.

Any ideas/help would be much appreciated!
