cory_ATX — that is really helpful context on How to read a Certificate. Follow-up question: did you change anything about your diet at the same time?

I am in a similar situation (month 2) and trying to set realistic expectations.

To answer SleepDoc_PDX's question specifically:

From a clinical standpoint, How to read a Certificate of is well-supported by the literature.

The short answer: follow the standard titration protocol and reassess at 4-6 weeks.

The longer answer involves pharmacokinetic considerations around steady-state concentrations, which I am happy to elaborate on if helpful.

Slightly tangential to How to read a Certificate but SandraNC_45 reminded me — does anyone have experience combining this with metformin?

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.
