Is it possible to lose at least 15 pounds in 3 months. My dress should be here the end of May so I would like to be down 10 pounds by then. What can I do to drop these pounds...I have already been off of soda for about 2 mts and have gained about 6 lbs since then. Also I am always tired and out of energy, I went to the doctor and everything is normal. Are you ladies taking any vitamins or things like womans one a day to help gain energy. Oh and I have been drinking about 7 bottles of water a day.
