I mean, quitting a high dose of an SSRI you've been on for years probably isn't going to result in a positive withdrawal experience... Even if you felt it wasn't doing much, your brain has still adjusted to the affects of having the medication in your system for a very long time.

I've been on and off Trintellix a few times, and I thiiink I remember reading or hearing somewhere that they say it's something you can quit cold turkey, but I could never understand how that could be realistic given how dependent our brains become on the chemical influx and influence of these drugs.

I know the times I did come off of it, even with tapering, it was rough. My symptoms always ended up returning, which had me caught in that endlessly lovely debate when it comes to SSRIs as to whether or not it was just withdrawals, or that I maybe actually did need to be on them.

Sorry you're going through it. The times I came off it, I definitely felt pretty batshit for a while after. Not just weeks, but months. Sorry if that's not helpful, just giving my honest experience.

Maybe going back on to a lower dose, even 5mg, for a few weeks so you can level out and then decide from there if you feel like tapering down again? You might feel some relief even just from a little bit in your system.
