I can see how EMLA can be a logistic nightmare, time consuming, never know how much area to cover so that you don’t waste it if electrologist doesn’t have speed or time to treat all hair in EMLA treated area.
I was IV sedated 5 times in my life. 3 for wisdom tooth extractions and 2 for a procedure. All were under 30 minutes. The 2 were Propofol done by an anesthesiologist. First 3 by an oral surgeon. The IV sedation does work in terms of you not feeling pain. I think they might still use local on you but you won’t know or feel it. But my only concern would be that you’ll need 14+ sessions and health and safety of doing frequent sedation over 2 hours each. Speak to the doctor about the safety and see what training and credentials he has for administering IV sedation. Each country has different standards of training for providers using anesthetics and I’d be a little more hesitant to go under IV so many times.
