Any Long Distance Cycling nuts out there?

Okay here's another crazy question.... Although my highest weight just 2 months ago was 237 pounds, I am crazy about long distance cycling. Like tour de France stuff. I regularly ride my bike anywhere from 25 miles on weekdays to 75 miles on a weekend morning and several times a year ride organized Century rides. I can complete 100 miles on a bike in 7 hours.

Does anyone know if getting the LapBand will make too much restiction on my hydration and nutrient requirements for this type of long distance cycling? I don't really require nutrients in mileage under 50 miles, but with the already reduced caloric intake sugars/carbs may become an issue on the road... I'm panicking about not being able to ride in the manner i'm accustomed to and wonder if anyone else enjoys this sport like me and how have they done post surgery?

My doctor just said, i'd do fine and i'd just do it better post lapBand, but i'd love to hear any real proven statistics. I know that it's counter intuitive for someone this heavy to be riding the distances on a bike that i do... but for whatever reason i never lost significant weight when riding but rather i just seemed to gain bulk.
