shangefan,
The soups weren't too bad. I kept getting a variety of Campbell's soup. I really didn't get too tired, but I kept everything spread out. For example, around 7 am or 8 am I would have the MetRx MRP; around 10 am I would have a protein bar that has 20g of protein (Clif Builder's Bar); at noon I would have the soup; around 3 pm I would have another protein bar; between 5 pm and 6 pm I would have soup again. Before bed, if I felt hungry, or didn't get enough protein, I would make a shake with MetRx Ultramyosen Protein. (One other thing about protein, sometimes I'd mix it with non-fat milk or just water.) I supplemented the soup (depending upon the number of calories in the soup) with a serving of apple sauce and/or no-carb Jello; water, spiked with Crystal Light Hydration or Green Tea On-The-Go packets.
There were times I ate a lot less than this b/c I wasn't hungry, but I thought I should try to get to 1,000 calories per day.
Like most anything else, once you get used to the band, eating is not too hard. Every now and then I do miss chips and other type snacks, but when I put my smaller clothes on, I overcome that urge.
Good luck to you!
