I usually feel the sedative effect within the hour, if you're talking physical. Added actual CW for the impact it has.

Mentally it seems to make it harder to pull together the urge to self injure. I can feel depressed or manic, but the anxiety giving way to a need to self injure just doesn't come.

It feels like when you're exhausted, but want to pull yourself up and keep running.
As much as you want to, mentally, you're too exhausted to pull together that feeling. So I cut myself less, but it's hard to track that.

Currently I'm on a relatively low dose, but it helps that a bit.
