I am still preop and also dreading my two week preop diet. With my doctor we are allowed 4 Bari-Essentials shakes a day if mixed with skim milk or 5 Bari-Essential shakes if mixed with water and sugarfree jello or sugarfree popscicles. Of course we are also to drink plenty of water but can add crystal light if we choose. Oh yea, unsweet coffee and tea are also an option. One more thing, we can have a cup of Swanson's low sodium chicken broth each day to break up the sweetness of everything else we can eat. Looking forward to the procedure but still dreading it too!
