Can anyone ident this pill for me? It's small, round and white; scored on one side with what looks like a 22 on one side of the scored line, and possibly a 0 on the other side of the scored line. On back, on the smooth side of the pill, is RDY.

This is supposed to be my Lamictal refill, but I'm not sure if it is? It doesn't look like the Lamictal I've taken in the past.
