Slightly tangential to Mass spectrometry for but mia_MS2 reminded me — has the insurance landscape changed recently?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Reading this thread on Mass spectrometry for hits close to home. Dad of 2 checking in — I started at 265 lbs and felt like I would tried everything.

11 months on tirz and I am a different person. Not just the 40 lbs lost — my energy, my mood, my relationship with food. All transformed.

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

marcus_mpls — that is really helpful context on Mass spectrometry for. Follow-up question: how long did you wait before increasing your dose?

I am in a similar situation (week 4) and trying to set realistic expectations.
