Also known as acupuncture i think. Has anyone done this to get rid of a habit, or lose weight or for something? My friend did it to stop eating junk and it worked and she lost weight. I want to do it to try to hypnotize myself to stop biting my nails!! I am feeling anxious right now, and keep biting them. Idk what it is. I feel like my heart is beating fast and i feel like i cant bite my nails fast enough! I always have to be doing something, is this an anxiety attack. Gosh idk..i think i want to try that, ths has to stop! Ive been biting my nails forever!
