I am writing a murder mystery for NaNoWriMo and need some help....I need a toxin that can either be breathed or ingested that will cause paralysis, while still leaving the victim conscious and able to feel. I know this is morbid...but this serial killer is very sick! Any ideas? Here is what I have considered Tetrodotoxin - While this is my first choice, i cant have the victim dying of respiratory failure first. Belladonna - but the side effects are so varied...I would worry the death would come of once again respiratory failure first. Curare, but everywhere I have read also says attacks the lungs first, and has to enter through blood stream Any other ideas? or know more about above materials that could be useful?
