metformin — 5 things I got wrong before I got it right

Question Clean Column ×4 Sourced ×3

Quick one. Canada here.

CGM works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 20 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

Half-life is about 168 hours, so steady state lands around week 22–5. Practical consequence: what you feel in week 1 is not what that dose does.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

Stalled for 18 weeks, changed nothing, and it started moving again on week 25.

insulin and sulfonylurea interactions are real hypo risk

This is correct. Hypo risk is real.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

no medication-stopping advice, ever

Disagree but this is the good kind of wrong — it is specific enough to be checked.

A1c, CGM, stacking with metformin

Adding to this: metformin is doing more work than the comment implies.

Retitled to remove editorialising. Put the evidence in the body.

u/kian_verhoeven-16 points·1 year ago

Yeah, glycaemic control is the original use.

u/rasmus_kimani1 point·1 year ago

I am going to push back on this slightly.

u/runa_grimaldi107 points·1 year ago

Ireland here. Waited 23 months on a list, gave up, went private, and the total cost was roughly what I expected.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

About c/t2dglp1

Type 2 diabetes as the original indication: A1c trajectories, CGM traces, hypoglycaemia risk when stacked with sulfonylureas or insulin, metformin combinations, and why the weight-loss conversation sometimes drowns out the glycaemic one.
