I recently started Nortriptyline just 2 days ago. I was wondering how long it takes to start working. I took it about a month ago however the doctor stopped as he thought I was hypomanic (bipolar) - any ways I had 2 cups of Starbuchs before I saw him and was a bit wired. It seemed like the last time I took it it almost started immediately. Just wondering what everyone else has experienced and how long it too before it took effect
