I have the same problem with the drop bars. An easy solution is to add bar top brake levers. I ride with my hands on the top of the bar (and can easily brake with the bar-tops) or, on the hood of the shifters. If you are looking for decent cycling gear in large sizes, try http://www.aerotechdesigns.com/ They are reasonably priced and I like the shorts better than the more expensive Terry brand. Keep pedalling! I'll be thinking about you when I'm working off my own excess weight from the seat of my bike!
