If you are very light, hanging is more difficult for you, i think. Complete and also partial. It can be longer time than you will die. The force for tightening of a rope is same as your weight. Help for you is use a maximaly effective noose (with lubricated knot for good tightening), or use some weights (heavy clothes and boots). Full hanging is maybe better for light person, he/she uses maximum of weight. If you want try partial, you try a position with maximum of weight transferred to the rope (standing, or sitting in air). Lying or sitting on a floor will be poor, i think.
