Sweet, I like that J&J is using S-ketamine then. I think the dissociative effects of ketamine are fantastic and beneficial, even though they can be surprising. At a low dose it likely won't be an issue.
Personally, I have no issues with the dissociative effects per se. However, studies have determined that they aren't related to the antidepressant effect. Fwiw, a full clinical dose feels like ~1/4 of a 'rail'. There's no introspective trip here, just slight drunkenness.
(Incidentally, we have some evidence that the metabolite that causes the effect can be blocked via concurrent CBD administration - without reducing the dissociative effect)
The standing appointment to get slightly high for a couple of hours every three days does get inconvenient (though it's not as problematic as the resultant insomnia). I expect esketamine will be more so, for less antidepressant effect. And, being a controlled substance, I'm concerned I'll be unable to increase my dosage to make up the difference.
