As someone who takes antidepressants this is nonsensical to me. I don’t feel 100% normal on an SSRI, I experience the normal side-effects of flat affect and weird tastes, etc. But the alternative is regular panic, exhaustion, indigestion, and general volatility that makes my life difficult and hard for others to interact with me.

If dissociation is better than regular PTSD, then go for it. We don’t expect people with hip replacements to have 100% mobility. We don’t expect cochlear implants to hear better than healthy ears. Mental health interventions have similar tradeoffs.

Exactly this - I don't believe that it's meant to be a "you're now completely fixed" type of solution, but it does seem like it would increase quality of life as it is meant to. Similar to SSRIs.
