Could someone please help me identify pills that I have found in my husbands briefcase. One is a round yellow pill with the letters DAN on top of the line and the numbers 5619 on the bottom and on the back is the number 5. Also there are little white pills that have the letters GG and 92 underneath. I am very confused and have searched the internet trying to find out what they could be before I worry. Thank you so much.[?]
