Also, I've seen that people who consume strychnine are said to have a garlic like odor on their breath, but would they be able to taste it as well? Would it actually taste garlic-y? Wiki says its one of the most bitter substances in the world; what could the murderer possibly do to conceal the taste? Could s/he put it in the victim's food or drink, and have him be none the wiser?
I've also looked up descriptions of the physical symptoms - spasming, convlusions, opisthotonos, impeded respiration, etc. But what would a person experiencing these symptoms be thinking? Would they even be thinking, or would their brain have shut down due to the pain? Is a person completely conscious and aware as this is going on? I'm also assuming death occurs when the person asphyxiates.
Does the victim's body often "freeze" in the state of opisthotonos? Or could the body "freeze" in a different more-convenient-for-the-author position? :P
And finally, what would this look like to the outside observer? Epileptic? Jerky? Spasmodic?
Any help is appreciated! Thank you!
