A friend drove me to the doctor to get the procedure done. Afterwards, my friend asked if I wanted to go by Lowes to get a measurement for a cabinet that I needed for one of the guest bathrooms. I said okay. When we got to Lowes, the employee took us to his work place where his computer was so we could give him the dimensions and other information. Well, while he was waiting for his computer to get started, I started getting sooooo sleepy to the point I could not keep my eyes open. The next thing I know, I placed my head down on his desk and fell asleep. My friend, who was with me, was in his 70's, and the Lowe's employee asked him if I was okay. My friend replied, "yeah he just had a roto rooter done." I think it was the sedation used before propofol because I never had an issue like that with my last 2 procedures.
