Bariatric surgery has most of the same upsides as GLP-1s and is a one-time cost. But I agree with the other commenters that "forever drug" is mostly fretting without an actual reason. The Hunger that engineered foods are deliberately designed to induce is a forever thing too, now there's a counterweapon.

If it sounded like I don’t think other people should take them, that was a mistake on my part.

I’m just really not what you’d think of as a model candidate for them, so I’m not quite ready to commit to my first and only, not exactly free, rest of my life pharmaceutical dependence.

That may not seem perfectly rational to some… but ya’know… I’m the one who has to live with my brain.
