I guess I'll just reiterate some good points that have already been mentioned here. If your spokes break when you're just riding along as you normally do, it's likely due to metal fatigue. Metal fatigue is cumulative. If you have existing spokes that are already metal fatigued, retruing and retensioning the wheel may make them last marginally longer but it won't fix the spoke damage that's already been done.

There are two main ways to metal fatigue a lot of spokes on a wheel. The first way is to undertension all the spokes. Even a wheel that looks true on the stand can be badly undertensioned. The second main way to ruin a lot of spokes is inconsistent tension. That can occur especially if you ride a long distance on a wheel with one or more broken spokes.

You can certainly replace broken spokes one by one, but that won't cure the other spokes that may already be badly metal fatigued and near failure. I did that myself last year when I wasn't willing to rebuild or replace my existing wheel. I wound up replacing seven or eight spokes which all broke within the space of a few months. No problems since then, but I clearly understand that the spokes that haven't already broken may be metal fatigued to an unknown extent. The ideal thing to do would be to replace all the old spokes with new ones or get a new wheel, but right now I'm okay with spending $2 and an hour to replace broken spokes one by one.

Car free tip: keep extra spokes on hand

I'd guess that at 188 pounds the OP's spoke problems aren't mainly due to rider weight. I'd suspect that at some point in time the wheels were ridden when they were badly undertensioned or way out of true. Re-tensioning and retruing the wheels won't fix the metal fatigue that's already occurred in the spokes.
