Get a hold of some morphine and anesthesia.
You will need to have all the stuff right there in front of you and ready to go, there is no time to take one and then go get the other ready.
Pop like 3-4 pills in one hit then immediately shoot yourself up with an extreme amount of anesthesia. You'll literally die in your sleep. I know because a friend of mine died in the operating room after she was shot with an excessive amount of anesthesia. She was there for a boob job, and that's all she wrote.
