I think you mean Hydromorphone, or Dilaudid. That's pretty powerful stuff compared to something like Hydrocodone and not something to be messing with. They use it for things like pain relief for people with cancer.
Why do you ask this?? A weeks worth is too much!! I hope your not thinking what i think you are..please be honest why do you want to know? You can talk about anything you want here, no worries..everybody here is caring and understanding! Please dont take that much!!! Talk here, talk about anything you want..get anything you want out on this forum because thats what its here for and we will do our best to help. If you are really planning on doing this..please think it over...its not worth it. You probably have a lot of family that would be VERY deeply effected by your actions! You need to talk about this first! If you feel like your going to, call 911..please!
