I read this hint in "Women's World" (May 28, 2012) issue and IT REALLY WORKS!!
When cutting back on sweets or other temptstions, it is much more powerful to say "I don't want it" rather than "I can't have it." Studies show that saying "I can't..." makes me feel deprived and weakens my resolve. By saying "I don't want...", I feel in control and more empowered to stay on track. Try it!!
