How long does the obesity injection procedure take?

It is difficult for me to make time on weekdays, so I am looking into treatments that I can receive after work. That led me to become interested in weight loss injections, but I have no idea how long the actual procedure should take. I am curious if it tends to take a long time from the consultation to the end, or if it finishes faster than expected. I would also like to know if I can return to my daily life immediately after receiving the injections. I am also curious to hear about your experiences regarding whether it was okay to go to work or have appointments the next day. If you could tell me how long I stayed at the clinic for my first injection and if there was anything I needed to prepare before or after the procedure, I would appreciate your feedback. Please share your experiences if you have received this treatment yourself!!!
