Something that's stuporous is slowed and muddled. When you first wake up in the morning, you may stumble around in a stuporous state.

When a person is stuporous, she is confused, sluggish, and foggy. A patient who's had surgery often wakes up feeling stuporous, and going without sleep for several days will leave almost anyone stuporous. If you're stuporous, you're in a stupor, or not quite fully conscious. In Latin, stupor means "insensibility, numbness, or dullness," from stupere, or "be stunned."
