I'm confused, I thought lantus had a low risk of hypoglycaemia?

(just b/c it has no peak effect)
I'm still in the honeymoon stage / early stages of type 1, so I take a small dose of lantus (only 3 units). I’ve felt low occasionally, but never had a true low i.e < 4 / 3.5mmol/l (72 - 63) – (I usually feel low under 5-6mmol/l)
My fasting numbers are much lower than your fasting numbers, 4 - 6 mmol/l (72-108), sometimes a bit over 6, except the last few days I've been 9.1, 9.1 (163) and 10.6 (190). I started off at 2 units, when my Dad mentioned the dose hardly seems worth it to the diabetes educator she said some of her patient take 1 unit!
I've been on lantus since 21/10.
