I AM BEING CHASED IN MY DREAMS BY FOOD!!

Began at a fav resturaunt of mine once inside I was about to order my entree when a case of Glucerna appeared... it chased me out & down the block. A bit startled I fell back to sleep and next I remember I was in the alley boxing a Protein shake which by the way ended up knocking me out cold!! Well I tell you today I drank my Glucerna with no trouble and sipping on my Protein shake as i write this! LOL. OK so there I said it my embarrassing food fright and now for the whole story. I am three days into my pre-op diet and my blood glucose levels are so flipping out on me, I am hypo one moment and hyper the next. I always have strange dreams or nightmares with that much flexing... I just wish it wasn't about being Chased by food or Fighting it. If you're laughing not to worry i'm not offended because my DH already busted himself laughing so hard after waking me out of it and listening to what happened. Hmmm....Am I alone in the food dreams department when you experience sharp blood sugar levels changes or begin reduce calories diets... hmmm could it be?? hope not lol 

Well I have my pre-op apointments all scheduled for the end of month. I actually had to call back and reschedule because of a time conflict. They're all booked now and it's really starting to feel even more real... WOW!! 

 I found I really like them and make them at home with a blender. I'm using unflavored Whey protein from london drugs, Skim milk, 8 Ice cubes crushed, 1/4 banana, 2 drops vanilla extract. YUMM! 

 Well I had my Holiday treat.. A Starbucks Smoothie in Orange Mango flavor with non fat milk, whey protein, fibre powder and ice. Yumm.. mmm.. filling and refreshing too. http://www.starbucks.com/menu/drinks/smoothies/orange-mango-smoothie?foodZone=9999#size=1084738&milk=61
