looking to lose 105#

My name is Julie. I've always struggled with my weight. At one point in time I had lost 40#, then was diagnosed with thyroid cancer and I gained it all back. I just can't stand it any more! I found this app and I'm so excited it will help me keep track of things and give me support. I would love to lose 105# as my long range goal. For the short term, we are going to Florida the end of March, I would like to lose 25#.
