Question about prep for surgery

I got my letter of approval AND my precertification letter from my insurance company over the weekend. I was out of town when they came but I'm going to be scheduling my surgery today.

I am a patient of Dr. James Davidson in Dallas.

I've been trying to find information on what I need to do to prepare for the surgery. Will he have me on a totally liquid diet and for how long?

Anyone out there who can give me some insight on what you had to do? I would really appreciate it!

Doctors all seem to have different programs pre-surgery.  From "Just don't eat anything after midnight before surgery" to all liquids for a couple of weeks.  I was put on a 2 shake and small (~400 calorie) meal a day program for 2 weeks.  Your doctor should provide you with a prep program that has guidance on your specific requirements.

 I only had to do clear liquids the day before surgery, but looks like every surgeon has a different protocol.  I dont really see the benefit of doing weeks of liquids pre-op other than to make you miserable. It is so much easier to do liquids after surgery. 

Thanks. I guess I'll just have to wait and see what they say. Hopefully someone from the office will call me back so I know what to do from this point out.
