> A lot of research has shown SNRI and SSRI antidepressants are actually great for nerve pain, e.g. gapapentin, pregabalin, duloxetine.

I'm well aware of this. If you read some more research the dosage prescribed for nerve pain is as I mentioned ~4xish of anti-deppresant dosage. More so I recommend you look into some research on withdrawal effects of antidepressants (of course there is less of it since drug companies have a vested interest in the actual lack of such research).

I take Amitriptyline at night (in addition to opioid patches and antiinflammatories). While I find it does have some analgesic properties; the real benefit is actually a side effect, the drowsiness means I actually get some sleep.
