Are you sure the suit is fitted properly? I have larger shoulders and chest than normal for someone my height. After I bought my wetsuit, I dropped 15lbs as well. What ended up happening was that the mid section of my wetsuit was too big and as a result I could feel water flowing up and down it which made me really cold. I bought a 3mm vest to put underneath and I was still getting cold. I use a pinnacle elastaprene 7mm with the merino wool and when I was heavier it was nice and toasty. I dive dry now except when hunting and even in the summer, I was getting cold diving wet. Although, that could be because the drysuit has turned me into a wuss!
