Hi guys. I'm young and very unhappy person. I really need to loose my weight to improve condition of my life. I never was skinny but my body weight is now doubled. I try lots if diets and nothing really help me. At the moment I have lots of health problems:short breath (although I quit smoking a few months ago), bad sleep, heartburn. I really have to change my life, but I have no power to fail again any ideas how to loose weight.
