Anyone have no special diet pre-op?

My surgeon put me on a low carb high lean protien diet when i seen him on 01/21.  He told me to really kick it into high gear when i got a surgery date.  I have to do 3 days all liquid and then 2 days clear liquid.  I have already warned everone that starting the 19th I might be cranky... LOL 

PRE-OP Liquid Diet - Geisinger Bariatric Surgery 2008-2009 I drink 3 low sugar/high protein shakes per day - one at each meal.

I can have 1-2 snacks per day:
light yogurt (8 oz)
SF pudding (4 oz)
SF cocoa (1 packet in 6 oz. milk)
tomato soup made w/ skim milk
skim or 1% milk (8 oz)

Only these fluids may be taken in addition to the shakes:
water
crystal light
decaf coffee or tea
bouillon or broth
decaf diet soft drinks [these won't be allowed afterwards unles FLAT]
SF jello
tomato or V8 juice
SF popsicle

GOAL: take 60-80 oz of fluid and 60 grams of protein each day. (Might need more fluid)



Here's my sample menu:

6 am - 12 oz decaf coffee
8 am - 8 oz No sugar added Carnation Instand Breakfast made w/ skim milk
10am - SF nonfat yogurt
4 oz. sf jello
12pm - 12 oz LowCarb SlimFast
2pm - 12 oz diet gingerale
4pm - 1 SF popsicle
16 oz. crystal light
6pm - 12 oz Carb Options
8pm - 4 oz sf pudding made w/ skim milk
8 oz V8 juice
