Hi tyaloha,
I do not know how a non-sleeping tiger will affect you - I have not tried it so far. I can only tell about the good experiences my friends had with a sleeping tiger and "a proud standing dragon". I gave them copies of the images in the book and now their difficulies with the neighbours have dissolved. The tiger energy on their right was overwhelming and they had no dragon at all on the left. I think that's the reason why the tiger should be sleeping - to have peace. If there's no one who actually knows in this forum, you can try it (9 days, 9 weeks) and if you get into trouble you can still replace it by a sleeping tiger. But maybe one of the moderators has some better suggestions than trial and error...
Love,
Astrid
