Preparing for my thyroidectomy

My surgery is Monday, Sept 13. I am preparing this week by taking Lugol's and a very low dose of PTU (25 mg daily). I have also been taking a high dose of Vitamin D(50,000 units weekly), Vitamin B12 (5000 mg weekly), Vitamin C (1000 mg daily), andCalcium (1000 mg daily) as well as magnesium (300 mg daily). I have been reading on visual imaging and visualizing the healing after. I have also had a swedish massage this week plan to have a hot stone with swedish massage on Friday as well as have a manicure and pedicure on Thursday with reflexology. These are my ways of relaxing that I usually do over a period of months time and am doing it in a week's time. I read that it's good to relax as much as possible. I also plan to listen to relaxing music (spa music) when I go under if I am allowed.....
