Gastric Sleeve Canada (getting surgeon to pick sleeve over bypass)

Hey guys, I was wondering for any fellow Canadians out there. How did you get your surgeon to let you do the sleeve over the bypass? I really, and I mean really, don't want to do the gastric bypass. I have really bad anemia which i've had since I was a child. To this day I don't have good control of it. My family doctor started me with 1 Iron tablet, then 2, then 2 irons and 2 B12 tablets and now I take 2 iron and 1 Vitamin C tablet and 2 b12 tablets.

I struggle like crazy with my anemia. I fall asleep in class, on the bus, I faint sometimes getting up from bed. I haven't even gotten my drivers license yet and I'm 20 because im afraid of falling asleep at the wheel.

I know my anemia will be affected with either surgery but I know the bypass will make it worse compared to the sleeve. I have my first assessment appointment in January to see the nurse. Do any of you have any tips or advise about how I could steer my surgeon into the direction of a gastric sleeve? Shiuld I just tell them my fears about the bypass?
