Naltrexone is a bleeding-edge medication used to manage substance abuse disorder, also known as being Addicted. It may be bought in pills for oral ingestion or in vials for intramuscular injection. Side effects include insomnia, anxiety, nausea, headaches and, as it is a natural opioid, the blocking of endorphins, thus inducing a period of chronic sadness for the duration of the treatment. Because Naltrexone was only recently discovered, and production only occurs in developed nations, acquiring it in Oceanyka is not a simple task.
