I have used diamine oxidase to be able to drink red wine without an instant headache. It worked well for me. But my reaction to gluten is to have diarrhea and cramping, which does not seem to fit with the reaction to histamine in bread discussed on those websites, so I haven't tried it.
If you don't have celiac disease, then theoretically there is no damage being done to your gut by eating gluten. Although the post-gluten misery can be pretty bad. The last time I accidentally ate a significant amount of gluten it took 3 weeks to completely clear my gut. Not going to do that again!
