The food noise came back three weeks after I reduced my dose, well before the weight moved, which tells me something about which effect tracks what.
What would genuinely help is knowing whether the quiet is the same mechanism as the appetite suppression or a separate one, because they seem to come and go on different schedules.
I would rather have one careful answer than five confident ones.

To build on this — the mechanism is more complex than "it makes you less hungry." GLP-1 agonists:
- Activate hypothalamic satiety centers (appetite reduction)
- Delay gastric emptying (prolonged fullness)
- Potentiate glucose-dependent insulin secretion
- Suppress glucagon secretion
- Modulate reward pathway dopaminergic signaling
- Reduce hepatic lipogenesis
- Have direct cardiovascular protective effects
It's a multi-target drug with systemic metabolic effects. Understanding the mechanism helps us predict and manage side effects.

Rebound hunger after missed dose of food noise: I missed my injection by 3 days due to a shipping delay and the hunger came ROARING back. Like a switch flipped. It was eye-opening to feel the difference.
This experience actually reinforced my understanding of what the medication does — it's not just "suppressing appetite," it's normalizing dysregulated hunger signaling. When the drug wears off, you feel the full force of what it was managing.

This matches mine closely enough to be worth saying so out loud. Posting only so the count is not one.
Clinical perspective, offered as context rather than as advice.
The GLP-1 and alcohol use disorder connection, relevant to food noise: observational data from Scandinavian registries shows reduced alcohol-related hospitalizations in GLP-1 agonist users[1].
The mechanism is plausible: GLP-1R is expressed in the mesolimbic reward pathway (VTA, nucleus accumbens). Agonism at these receptors may reduce the reinforcing properties of alcohol, similar to the reduction in "food noise."
RCTs for GLP-1 agonists in AUD are now underway. If positive, this would be a paradigm-shifting repurposing of existing medications.
