Hi detroit, how long have you been on the diet?
I am now 4 days complete. I only wanted to give this diet a try for a month, but I wanted to give as close to 100% as possible for the month. Like you, i thought Athletic Greens was a bit pricey. Based on amazon reviews, I ordered Green Vibrance, which seems to be a similar product?http://www.amazon.com/Vibrant-Health-Green-Vibrance-Family/dp/B000NDME6C/ref=sr_1_1?ie=UTF8&qid=1300334917&sr=8-1
I actually just ordered it a few hours ago, so I dont have any feedback for you, but it seems like a decent alternative. I'll let you know how it goes once I try it this weekend!
Good luck with your diet!
