I had to take a nap every day for the first 2 weeks. Then someone sugested potasium, and I got on Centrum carb assist. Now I am feeling much better. I have found it hard to stick with the 20 g in the beginning also. I love spinach salids with cucumber and a boiled egg, green onion, sometimes even grated cheese or deli turkey on top. It was like a full power meal for me. Good luck.
