I have accidentally doubled my dose of Zoloft before. It's nothing I would call a high.
This isn't up for debate, I'm fairly well versed in pharmacology.
Zoloft does not inhibit the serotonin transporter, SERT, at a quick enough rate to produce even "MDAI-type" euphoria, and has only negligible affinity for the DAT. It is not a direct agonist of Dx or 5HT2x receptors, nor an antagonist at NMDA receptors. It has no affinity for CB type receptors. It will not bind to any opioid receptors, or at any GABA-ergic site.
All of these things can be backed up by a multitude of research articles.
Unfortunately, the methods I have listed are the *only* ways to produce a "high" in the human brain, and Zoloft does none of them.
If we accept your opinion that zoloft got you high, we are forced to consider one of three options:
1. You're a lying troll
2. You got placebo-ed hard
3. You are actually a literal mutant whose brain is wildly different than anything seen in science ever before. Perhaps you're from outer-space?
E.T, is that you?
