Follow-Up:
I was taking Ambien every second or third night for the pasttwo weeks until last night! About 45 minutes after taking one (10mg) I watched the walls of my bathroom "breathe." I was very much aware at the moment I was having hallucinations. The walls moved in a fluid-like motion and my hands were "trailing" like the Matrix movie. Yikes, spoke with my Dr. today - I will not be taking Ambien again...
