Thanks for the mod and the time you have put into it!

I have one suggestion regarding using your new narcotics when keeping a creature unconscious.

If you give a creature 100 vanilla narcotics, they will regen 4000 torpor over 800 seconds. Since the torpor won't go down again for another 13 minutes while this is happening, you can do other things while waiting for the creature to tame.

The narotics from your mod do all of their work in only 8 seconds, meaning the creatures torpor is going to start dropping again almost immediately after your narcotic increases it.

I love the arrows, they save a lot of time, but feeding the narcotics to unconscious creatures is of no use to me. I will tranq them with your arrows, but still keep them asleep with the standard narcotics. With yours I have to babysit the creature more, knowing its torpor is always draining.

I would suggest:

Blue: 400 over 80 seconds
Purple: 2000 over 400 seconds
Yellow: 4000 over 800 seconds
Red: 8000 over 1600 seconds
Black: 20000 over 4000 seconds

This will match the rate of the standard narcotics and will allow people to reap the benefits of your mod's narcotics, instead of using just your arrows and sticking with the more efficient vanilla narcotics for keeping the creature asleep.
