All the time. I ended up buying a spinner ring (like this one but I bought it at a store) that I wear pretty much 24/7. This one works really well for me because I can dig my fingernails into it and "pick" at the ring. It also just gives my hands something to do when I'm sitting in meetings or watching TV and would otherwise have idle hands.
I have a chain spinner ring (like this one) that I've had for years and I wear almost all the time. I like this one in particular because I can hook my fingernails into the chain links and approximate that picking sensation. After being broken in, it spins quite nicely and I can take it off and fiddle with it using both hands. It's helped me immensely.
