It's mostly appetite suppressing. Affects the perception of hunger and the brain/reward function of eating, which must also be part of what also helps for drug and alcohol addiction.

It IME doesn't act like an anti-depressant/SSRI which can affect your enthusiasm/desire for your job.

Absolutely life changing drug for me.

But what if this self-described obsession translates into burnout? Does it actually make you good or just work more compared to your peers? Can you maintain it for the rest of your career?

(I'm just concerned; I've seen many people good at and super into their job end up with burnout, often multiple times because they keep thinking "I used to be good at this!", "I enjoy this!", etc instead of accepting that it was never sustainable in the first place. I suspect people's nervous systems etc are more resilient in their 20's, which is why most people with burnout only start to run into it in their 30's)

It's a week-by-week injection - you can always stop taking it if you're unhappy with the effects.

Another N=1, I've noticed zero impact on my desire to engage in my normal obsessions while on GLP-1.

What GLP-1 did (initially) was give me horrible insomnia that peaked a couple of days after taking the injection so I had to time my dosage so that I suffered through that on the weekend. That got better over time and eventually went away after about 6 weeks.

Regardless, as another poster mentioned, it's a weekly injection and if you don't like the effects you can stop taking it.

I was excited about effects like this and think they’re entirely absent unless you’re obsessed with food-related app development or something else related to appetite.

N=1, I've been on GLP-1s for a long time and continue to be an obsessive.

I take it; still obsessed.
