Trintellix? Happy New Year!! I want to stop talking Trintellix. How would I go about doing this?

Hi, Seascape! Happy New Year to you also!
No, you can't stop taking it cold turkey:
"Do not stop using Trintellix suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine."
You'll need to talk with your doctor about why you want to stop taking the medication and then get a tapering dosage schedule to follow if she/he agrees.
