First day with #FreeStyleLibre2 and I have questions. First, it's giving readings that are pretty consistently 20+ points lower than my #TrueMetrix, so how do I know which one is more accurate? Second, I got a reading of 69 mg/dl while I was napping and the alarm went off. Every source I look at says under 70 is bad, except #DrEricBerg (who may be shady) who thinks it's fine to be 50-70 if you're fasting and on #Keto. Is there a reputable source making the same claim? #PleaseBoost
