Hi Akeun,

Yes, SSRIs can influence one's sleep quality and quantity. However, the types of changes can vary from person to person and, indeed, from sleep stage to sleep stage.

One study found that taking an SSRI actually increased Slow Wave Sleep (a.k.a Deep Sleep) but another study found that SSRIs shorted total sleep time, increased the number of nightly awakenings, and led to a degradation of sleep quality.  One Zeo user found that their SSRI drug completely suppressed REM sleep, affecting their ability to quickly recall information.

As with any prescribed drug, it's best to make any changes in use after discussing the drug's effects with your physician.  For some, the positive effects of the drug outweigh the negatives; for others a different course of treatment is needed.  Supplying any Zeo data and SleepJournal information to your physician might be a big help in weighting a drug's effects on sleep.

Sleep Well!

Yes. My sleep MD told me I have REM-dependent sleep apnea. In my most recent two sleep studies, they had a very difficult time detecting apnea as such because I had little, if any, REM sleep. He indicated my SNRI usage suppressed REM sleep. At most, my Zeo shows 40 min of REM sleep at night...never more than 15 min at a time. The good thing is that I no longer need a CPAP. Obviously, the lack of REM is serious. I use SNRIs for depression and fibromyalgia so I don't have options now.

My experience with Benzodiazapines (http://buildbettersleep.com/how-i-quit-benzodiazapines-ativan/) seems to mirror most SSRI people as well. With the Zeo, I could clearly see a significant effect on Deep Sleep. Funny how SSRI's seem to affect sleep in different, but equally disruptive, ways.
