The 3.1 within 20 minutes just means you are heading down.
Do you check your dexcom against a glucometer at all? Mine tends to under-read, particularly in the first 24 hours. eg this morning it said I was 4 when I was actually 5.6....
Do you have any idea why you are suddenly getting more hypos? eg some people find their insulin needs change in warmer weather?
Virtual hugs, how I hate hypos. (My team are putting me on a pump because of them).
Yes I usually check my dexcom against a glucometer because when I'm low the glucometer usually says I'm lower than what the dexcom says (1 to 1.5 mmol/L lower). I didn't check my low this morning because I knew I had to treat it no matter what the number said.
Yes, I know -- or suspect -- why I'm getting the lows. My Dr tripled my dose of lantus because I was constantly high, in the 20s. The hospital Dr yesterday halved the dose but I had none last night (as per his request). So I don't know why I'm going low right now... the lantus should have worn off well and truly
Edit: My Dr is very, very good. I'm not blaming him in any way, just explaining why I think I'm having such a rough trot
