I am on my 6th day of pre-op diet. I was instructed to take opti-fast 900 (4 packages/day and as much non starch veggies as I like for 2 weeks.

My problem is with the Opti-fast. I can tolerate the taste / texture, but within 15-30 of drinking the Opti-fast I become ill (nauseated, vomiting, tired, etc).

I have tried taking it as the instructions say to make it and drink it. I've tried making it with ice in a blender and eating it. I've tried taking only 1/2 pack to an 1/8th of a pack at a time, eating with / without veggies but each time I've ended up with the same reaction.

Has any one else had the same thing? or any suggestions on how to make it stay in me?

Thanks

i start mine tomorrow hope i dont hav the same prob... i hope it changes

i'm on my 3rd week of opti fast and i' ve had no problems

i make it with crushed ice and have had no ill side effects

I drank nothing but Optifast for 8 weeks but was on 5 shakes a day and it was less potent - I think it was Optifast 800. Make sure you have plenty of liquids a day - it makes a big difference. I was told to have at least 64 ounces of sugar free beverages a day like crystal light, decaf tea and coffee and water. Try that and see if it makes a difference.

I had an allergic reaction to the Opti-Fast. I swelled up like a balloon all in my face after drinking it. My Dr. told me to try slim fast made with soy milk instead of the Opti-fast - and that seemed to clear things up for me.

hi alway sme

I had a reaction so bad I couldnt take it. I was so scared the surgeon wouldnt operate coz i wouldnt lose enough weight before the op. My dietitan put me on a high protein extermely low carb low fat diet for 2 weeks. I lost 19 pounds!!!!

It was easier for me than optifast as it made me sooooooooo sick

hope that helps
