“How long does it take to recover from deep sedation?”

Around 24 hrs to be fully back to your pre surgery state

That's really too open ended of a question to answer with anything that is beneficial to you. Your wake up time depends on what meds you got, how long you received them, your body's ability to metabolize or breathe off inhaled agents, the procedure and what effects it has on your CNS, how much post operative pain medication your procedure necessitates, etc., as well as whatever other medical issues you have will contribute. Assume 15 minutes to 2 hours as a range depending on the above.

It depends on what medication is used to give deep sedation. Propofol has the shortest recovery.
