Reading this thread on Has anyone dealt with hits close to home. Dad of 2 checking in — I started at 297 lbs and felt like I would tried everything.

13 months on tirz and I am a different person. Not just the 72 lbs lost — my energy, my mood, my relationship with food. All transformed.

If you are on the fence about Has anyone dealt — take the leap. It was the best health decision I have ever made. ❤️

As a healthcare provider, I want to add some clinical context to this discussion on Has anyone dealt with moisture content.

Building on what EndoResFellow said — the evidence base here is well-established. The key publications to reference are from the SELECT program[1].

Key clinical points:

  1. Efficacy is dose-dependent and typically requires 4-5 weeks to reach steady state
  2. Side effect profile is predictable and usually manageable with standard protocols
  3. Monitoring should include baseline labs and follow-up at 3-month intervals
  4. Patient education significantly improves outcomes and adherence

Standard disclaimer: this is educational, not individualized medical advice.
