You definitely need to have somebody drive you there and back. In my written instructions they said that if I didn't have a driver come with me and stay for the procedure and drive me home, they would cancel the procedure. Bold, underlined and highlighted. You will be out of it to a degree for most of the day due to the general anesthesia. It is also best to have someone with you as the "designated note-taker" when the doctor tells you what he/she found and tell the doctor that you have a designated note taker. Both times I had the procedure I have no memory of what the doctor told me about what he found. I was glad to have my dad with me as the designated note taker and driver.
