People react differently to drugs. I use to take two or three vicodin at a time and they would pick me up because the pain would go away. Pain zaps your energy.
How would you react taking 97 vicodin in a day?
And I think you probably react differently at different times. I had some vicodin for pain before I could schedule a root canal. Some times it worked, sometimes the same dosage laid me out. And you're right about pain zapping your energy. I didn't feel quite right for about 2 weeks, whether I was on the pills or not.
