YUCK.. Slim Fast..

I am currently doing the pre-surgical diet and my physician wants me to do the Slim-Fast diet for 2 weeks to aid in shrinking the liver.
But I have a problem.  I can't get the Slim-Fast down. 

Well..I can get it down..but it comes right back up. 
I have tried all kinds of flavors and it is all the same. 

Does anyone have any suggestions as to what I can do?

Thanks,
JAN 

I have tried the vanilla flavor and blended it with ice and bananas or frozen strawberries.

Slimfast is awful. I can't even choke it down. I also noticed that it's really not that great in nutrition for the calories. I would call the doctor and see if you can try another brand or type. I used Carnation Instant Breakfast, which comes in sugar free. I still drink it. It tastes SO much better than Slimfast. Also, somewhat better for you, especially if you will actually drink it and stick to the diet. Afterwords you will still need to drink liquids, so it's better to find something you can stand now.

I also like the Carnation Instant Breakfast (sugar free)!
