Well, your reality checks will never fail for you in waking life, so be sure to perform a few if you think you are dreaming. For the dream state, I always go with the nose pinch RC. It has never failed to work in the dream state before (for me anyway). It is my most trusted RC and I always perform it several times in a row. If it seems to be getting worse as you practice, go ahead and take a break from ADA for a bit.
