Hello, I have been on Lithium for about 7 years, since that time, I have severe Dry mouth, my tongue is all cracked and my gums are receding so badly that I may need grafting, I am only 55 years old. I also gained 35 pounds on Lithium. I am switching to Geodon mostly because of my gums and I don't want to lose my teeth, but the weight loss would sure help me feel less embarrassed about how I look. I am supposed to start the Geodon tomorrow morning.
