I have been taking Sertraline, 25 mg., since 10/20/22, 1X daily. I was getting at most 3 hours of broken sleep, after several days on medication I started getting 5 to 7 hours of sleep. This medication has reduced anxiety and panic attacks. I have not had any negative side effects from this medication. I was also given Xanax prior to Sertraline, but only took one, since I was unhappy feeling sluggish, lethargic and unsteady. Hope this helps you.
