How long should I schedule the Botox procedure?

Every time I look in the mirror, I get upset because the deep wrinkles between my eyebrows and on my forehead make me look so fierce. My friends and acquaintances have strongly recommended Botox, saying it is the best way to smooth out wrinkles. I’ve been interested for a while, but I kept putting it off because I’m terrified of needles. However, I’ve finally decided to take the plunge and make an appointment. Since I work, I plan to squeeze in a quick visit during my weekday lunch break or right after work. How long does it take in total, from the consultation to the anesthesia and the actual Botox procedure? If the time spent lying on the bed is short, it would be perfect for a quick stop during lunch. I tend to be quite timid, so I desperately need reviews from those who have been there to see if the procedure is short and finishes quickly. Please save me from the woes of a working professional! 😢😢😢
