I have been taking citalopram for 2 years for migraine prevention. I also grind my teeth at night. A sleep study I took about two and a half years ago disclosed no sleep apnea.
The report from my zeo, which I recently purchased, consistently shows that I am awake most of the night. It shows that I have been awake for three hours after retiring, and before beginning any REM and/or light sleep, even though, in the morning, I don't feel as if I was awake for a long time before falling asleep. The report for the night shows 1.53 hours of Rem sleep and only .08 of deep sleep. I don't feel sleep deprived but am puzzled by the results of the monitoring.
Can you shed any light on these results? Is the zeo analysis based on muscles in the face (that is, might it be record that I am awake based on teeth grinding when I am actually asleep?) or actual brain waves? Could the citalopram be masking the brain waves during sleep in some way?
