RCs stop working after lucidity?

Counting fingers and blocking the nose are the two RCs I've been using the most, and they are the two RCs I've had the most success with. Unfortunately, they no longer work after I've become lucid. I have no idea why this is. But if I've used these RCs to successfully induce lucidity, but later in the dream want to use them for clarity/stability issues, they often don't work. I'll be able to count my 10 fingers clearly, and I won't be able to breather through my nose, just like in waking life.

Have anyone ever experienced anything similar?
