Most important info: front or back wheel spoke breaks, hub or nipple end, if back drive or opposite side of wheel?

If you are breaking front spokes the wheel will likely need to go (have LBS confirm) due to pot hole impact stress putting it out of round. If the back you might just be overstressing due to weight and distance. You could replace spokes and check tension periodically and keep it going. You could also rebuild yourself.

I should know, me: 240lb rider who breaks spokes all the time. It is the bane of my biking existence.
