I have been on 50 mg of Pristiq for 5 weeks. I have always taken it in the morning, but my sleep habits are getting worse. I feel incredible and really want to continue taking it; however, I don't want to be dependent on a sleeping aid. Will this symptom subside with time? Does anyone have any experience with this? I noticed other similar questions, but those individuals were taking it at night. I always take it in the morning. Thanks so much!
