i need to know what a yellowish colored pill is round and would have a word that starts with a s around the pill. A girl i know had a seizure from two of these pills and we do not know what it was. Someone said it was a vallium, but i can not find a picture that even resembles it. The pill also did not have the line where you could break it in half. This is all that i know of the pill. Any information could help. Thanks
