Yes, sadly it is a serious question. It was accidentally, of course. He thought it was water, that he was using to break down, and draw up a 30 mg morphine pill with, he filled the syringe, a full 100 units, with a shot mixed of sprite and morphine, it looked too clear, I noticed after he drew it up, like it was really watery. And it was very hard to plunge and push it through, but he forced it, not knowing why he was having trouble, because that had never happened before. Then as he cleaned the syringe, he quirted the rinse in his mouth and tasted the citric syrup, realizing he shot soda into his veins and started freaking out. He was drunk when he did this.. and there was no way he could have known by the way he did things until after. It wasn't exactly sprite, it was an off brand lemon lime soda. Completely clear liquid. He complained of his arm burning, his head hurting, his chest hurting, difficulty breathing, losing temporary hearing in one ear, feeling sick, I searched all over the internet trying to find an at home solution, or remedy, and what the repercussions were, or damage it would do to his body- all I found was a few things saying the syrup would do something, that went to his brain, and something stops working and death, or air bubbles, something with the brain, and death. The only solution or suggestion I could find telling what to do next, was to shoot water repeatedly into your veins to try and push it out, or flush it, and he said the only way to really push it out of his veins was to push something other than just water, so he drew up part of another morphine 30, with a lot of water and shot that in his veins. After that, he claimed to feel a lot better.. but his head still hurt, and he still didn't feel good. He's been sleeping off and on, the last few hours, I am monitoring him, and his breathing, to make sure he's okay. Any suggestions? Anyone ever done anything similar, or heard of/saw someone else..?
