I'm also an AB Little so I don't know if the question is directed at me personally, but I'll answer anyway lol.
Pacis are pretty darn relaxing, even when I'm not in little space I enjoy using one to relax on tasks like watching tv, playing video games, or doing homework.
My favorite is a Baby Pants one I got off of Amazon extremely cheaply. LittleForBig is good too but it irritates the sides of my hard palette personally; but that's just because I have a relatively small mouth for an adult. The average user should have no problems with it.
They're definitely worth a try. You could also try baby sized ones if you want; but they're not nearly as satisfying and can cause jaw cramping with extended use.
I was just a DL who wanted to try a paci and a slipped into being an AB.
I got my paci's from pacifiers r us a while back and I fell in love with them. I often forget that I am sucking on them if I have them in for a while.
