After triying to promote one of my websites with Adwords I saw my CPM fall from 10.81 to 8.41 in 5 days. Should I wait a bit and see if it recovers next month, or should I stop now?

That's a natural flux in CPM from my experience.
In fact, CPM can range from 25-50% or more and be "natural". Depends very much on the site.
