Michelle Byrd answered question 1/18/2008 I'm 120lbs. I'm 5'3". How Can I Get A Dramatic Weight Loss Without Just Sticking To Dreadful Diets And Exercising? And Are 13 Year Olds Allowed To Buy The Slim-quick Drinks From The Stores? Water. If you stop drinking all other beverages and stick to water, you won't believe how much weight you'll lose. My friend stop drinking sodas and things and she went from a 14 to a 7 in 3 months. She's now a 4. Give it a try, it can't hurt.
