Target sells a black bean soup already prepared like someone had mentioned. Its prefect for the liquid stay and u feel like u have real food. Protein powders i love syntrax nectar. U can only buy it online or i have only found it there. I bought from the sweets line and its like having chocolate milk. Its non gritty whey and onde mixed doesnt seperate out bad, i make the whole days in the mrning and measure out when the time comes. Best part its affordable i think i spent 36 at bariatricchoice.com and its a huge bucket. Syntrax has koolaide like flavors, juice, unflavored and others. I spent three months picking out my powder cause i am so picky. It has made my liquid diet easier to get through. I am trykng the unflavored in jello i made later. Good luck
