I am sorry I can't provide a lot of information, but a memory slammed into me that made me need to research.

Color- almost a shade darker than baby blue?
Shape- oval/capsule in shape (it was not a capsule)
Possible numbers 5, 7, 9 no order
Country of origin- most likely a US drug, issued in the '90's

It was a dissolving pill that had a strange taste to it, kind of 'sweet-ish' that made me feel almost numb? From what got into my system I know that I must have passed out from it.

Any help would be appreciated
