Slightly tangential to Tachyphylaxis vs but FranDenver reminded me β€” 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 β€” I did search first.

Thanks for sharing this, FranDenver. A few questions about your Tachyphylaxis vs experience:

  1. What dose did you start at?
  2. How long before you noticed side effects improving?
  3. Did your provider have any specific recommendations about Tachyphylaxis?

I am in a similar boat and trying to learn from others' experiences before my next appointment.

OP here β€” wow, did not expect this much response! Thank you all for the thoughtful replies on Tachyphylaxis vs.

To answer Dr.LeslieOBGYN: I started tracking everything in a spreadsheet from day 1.

Quick update: I will post a proper update thread soon. Thanks again for the evidence-based discussion β€” this is exactly why I posted in a science-based community. πŸ™
