This is where I part company with the consensus forming above. I would be careful about how confidently the flatness reports get attributed. Rapid weight loss, a large deficit and disrupted sleep produce low mood on their own, and separating that from a drug effect is genuinely hard.

Correct me if the detail matters more than I have assumed.

The weight came off and the harder part started, which is not what any of the material I read had prepared me for.

Mood changes on mental health: I want to be transparent — I went through a rough patch emotionally around month 3. Not depression exactly, but a weird flatness. Food was my main coping mechanism and without that, I had to develop new ones.

Therapy has been essential. I'd strongly recommend anyone starting GLP-1 therapy also invest in mental health support. The physical transformation is only half the journey.

Positive side effects of mental health that surprised me:

  1. Clearer skin — inflammation reduction improved my rosacea
  2. Better sleep — weight loss resolved mild sleep apnea
  3. Improved libido — better body image + improved cardiovascular health
  4. Less joint pain — obvious mechanical benefit
  5. More energy — metabolic improvements across the board

Not everything about GLP-1 therapy is a struggle. There are genuinely wonderful changes too. ✨

Following on from DeniseRN_TPA — and this may be the naive question:

Was that from a primary source or from a summary of one?

Reporting back.

Follow-up — I put something in the gap where food used to be rather than waiting for the gap to close on its own. That was the part nobody told me.
