I have not tried those shakes, I buy whey protein powder from any health food stores, low carb of course, look around, some are better than others, I have tried the Gourmet whey carmel, very sweet, but good, the chocholate peanut butter I did not like.

It may be cheaper to buy a hugh pale of whey powder.

I too am on Prozac, and have been for 9 years. I have been low carbing since last week of august 2002, and Im losing fine. So, im sure your gonna be fine, you may lose a little slower than the average person, I do.

Also, Jamieson ultra slim down has a zero carb vanilla protein powder thats not bad, add some davinzi syrup, or whatever and its good. I got I at HY Zales.

I always put a splash of whipping cream in my shakes, and shake em up, makes a hugh differance.
