If I'm losing just fine, but I stop losing a couple days after I start getting out of bed on the other side, and thats the only thing I do differently, does it mean that getting out of bed on the left causes stalls?? My weight loss stops and starts for reasons known only to my buttcheeks. There are surely a small percentage of people who are sensitive to aspartame or ANY sweetener, but IMO not enough studies have been done to PROVE a causal relationship.
