Phentermine and Surgery Risks?

20yrsold, 5’1. I havebeen taking phentermine for the past year on andoff to cope with binge eating disorder. Dec/jan was on the stronger version of the drug. I stopped and started back on the regular. I have a rhinoplasty in turkey with a certified ENT doctor on April 17th. He advised me to stop the drug 2 weeks before. I am stopping today April 3rd. I am scared if I will still have risks even though I am stopping 16 days before. Is this possible/ what are the risks. I’m paranoid/cold feet.
