First week on Reta - impact on blood glucose is crazy

I got myself a CGM and monitored my blood sugar a couple of weeks before starting Reta and then after the first dose.

I was about to be diagnosed as diabetic, blood sugar basically never under 120, spiking after eating to 170 and occasionally higher.
Since day one(!) after Reta - basically 100% of the time glucose is within 80-110 with no spikes, even after a high sugar treat it doesn’t spike, just slow steady moderate rise and then back to normal.

I literally bought a traditional glucometer to double check the results because I thought the CGM was malfunctioning, but nope, it actually is this perfect right away.
It’s fucking unreal.

Too early to say anything about weight, but that alone makes it worth it.
