Fast drug isn't supposed to be sleep. It is supposed to be greatly slowed metabolism so that 1 subjective week would be 60 weeks to non drugged individuals. Nothing says you need ANY medical support. You're able to eat and drink so dehydration is not an issue.
Please cite a source for these issues.
You don't need a source to realize that only being able to move at 1/60th speed is going to really affect your ability to do things a lot, and make everyday life very dangerous. You'd be almost like someone who is paralyzed, except with just enough ability to move to get yourself into trouble. A drug like this is also going to have massive side effects. Something messing with the human metabolism that much is going to do a number on you.
Here's a list that I came up with, no need to pile them all on at once, it might be better just to make Medic and endurance rolls:
Side effects may include Hallucinations, Memory Loss, Priapism, Blood Clots, Compulsive Behaviors, Stevens-Johnson Syndrome, Frequent and Violent Bowl Movements, Loss of Bladder Control, Headaches, and Dizziness, Anxiety, Restlessness, F
ast heartbeat, Fever, Sweating, Muscle spasms, Twitching, Nausea, and Vomiting, Do not drive or attempt to operate heavy machinery while on Fast Drug (TM).
Talk with your physician about whether Fast Drug (TM) is right for you!
