The easiest thing I can think of to do is build a faraday cage to go into but that isn't wearable or portable. It would actually work, though, if constructed out of the right materials.

The good news is you're near lots of Home Depots. Go to one and see if they have copper tape or at worst case ducting tape. (not duct tape like the grey stuff. The metal stuff.)

Find a very large cardboard box, like a fridge box or something, big enough to get into and sleep, work, etc.

Overlap the tape on the box so it becomes a screen grid and then connect a wire from the cage to ground. Of course you would do this on a plug with

ONLY the ground wire connected and none of the other two. Make sure a ground wire contacts every strip of tape so be methodical when you lay out the tape. Electrical tape, heat gun, maybe washers and nuts?

When you go into the faraday cage the transmissions will be shunted to ground.

The box should be free, tape fairly cheap and the ground wire easy to come by.

I know that seems weird but a faraday cage is standard security practice.

That's a start at least. Faraday for instant relief. Jammer for long term.
