I've had a box of pennies for about 2 weeks now. I searched a few rolls, but then a couple of teeth were in extreme pain and it's no fun to do anything while in a lot of pain. It was excrutiating. There were a few nights when I couldn't fall asleep because of the pain. Took a Vicodin that I had left over from when I hurt my arm. They worked twice, then quit working. Went to the hospital Saturday night because I had no sleep for almost 40 hours and was in extreme pain. Of course the only thing they did was give me some Percocets. They worked that night, then the next time I took some, they quit working again. I finally got the teeth taken care of today and can now go back to hunting rolls pain-free. Sorry for rambling. lol
