Wonderslim or Medifast Bariatrics anyone?

Have any of the pre-ops or "stuck" post-ops tried either?   I hear both are good but don't know anyone that's actually tried them.   Went to a new program/support group this past week and they have their pre-ops buy a "2-week program" that includes 3-5 protein shakes a day just like these vs. figuring your own way through clear liquids.   They also use it post op as needed to get in their 100-150gm protein requirements.   

have not heard of them

I think I've looked at the Wonderslim bars on Diet Direct and Bariatric Choice but thought they were high in sugar.  I don't know anything about their shakes.

I did notice some of the things are not in OUR protocol but other are.  Philly mac and cheese for instance is and gets good reviews.  I stay away from pasta, but that one looks interesting.  I've got two tubs of Unjury laying here so I don't want to spend any more $ unless I get a good review on these things from somebody.  Thanks Julia!

I tried some medifast samples and didn't find them to be filling and thought they were expensive.  Same with Herbal Life.
