I am on Aventyl (Nortriptyline) since some weeks. I now take 75 mg a day.
I started having insomnia 3 days ago, falling asleep only at around 3 am or 5 am.
My psychiatrist said that I have insomnia because of anxiety. I am not feeling anxious actually.
Do you think that Nortriptyline can cause insomnia or is it unlikely?
