Can anyone tell me what the drug"misty's" is?

[fettes5]

Could someone please tell me exactly what this tablet is. It's oval white with a "10" on one side and,what looks like an "A" on the other. The "A" has a slightly lowered "-" in the "A"itself. I am told the street name is "misty's". It is supposed to be a sleeping drug but i need to know it's proper medical name so i can research it on the medical websites. Any ID help would be appreciated quickly!

Hi it is morphine sulphate, will give you a good night sleep but probably not the best option, maybe amatriptamine or zolpiderm would be better options, I hope this helps
