I was also getting dizzy everytime I got up. The last two to three weeks have been much better though. I think it's because our bodies r adjusting and I'm finally eating more regularly and getting enough protein in. I found these protein drinks at Walmart called, core power, the light ones have 20 g of protein and r 150 calories. They taste great, no chalkie taste. The regular ones have 26 g of protein and r 240 calories. I wasn't too fond of the vanilla but all the others I love. They are about 2.50 a piece but they are filling and help me to get my protein in.
