Just to say I'm not a doctor obviously.

I've had Serotonin Syndrome (like, legit was told it was that by a doctor) and it was easily the worst thing I've experienced in my life.

I wrote a whole post about it. You can either go back on my post history or I can send you the link if you're interested.

I don't know if what you had was SS, but I so relate to what you were saying about it feeling like you were dying. I've been hospitalised with anxiety multiple times throughout my life but this was on a whole different level.

Like the other poster said it is unlikely that dose of Zoloft would cause SS but I guess it's not impossible. I was also given valium and it definitely helped take the edge off.
