is vitamin D 50,000 IU daily too much?

I am getting ready to have the gastric sleeve weightloss surgery done. I am severely low on Vitamin D. My regular doctor put me on vitamin D 50,000 IU once per week but the bariatric surgeon wants me to start taking it daily for months. I told my regular doctor and he said NO WAY! Now I have the battle of the doctors. I checked with my all time favorite pharmacist and he agreed with my regular doctor. What should I do?
