Can anyone please help me figure out this 1/2 pill I found on my bathroom floor? It's light blue, oval with nothing on the back and since it is not a whole pill I am only able to read the first (or last) number on the front, which is either begins with the number 9 or ends with the number 6. The number next to it could be an 8 or a 3 but I can't be sure. Any help would be greatly appreciated. Thanks!
