Hi,
I am not sure about the pharmacies. If I am honest, after surviving as a T1 in the days before test strips, I wouldn't worry too much about 1 night. I would, bearing in mind that it is not you, but your duaghter, get up during the night to check how she was perhaps, but I certainly wouldn't be driving round the county looking for a pharamcy.
Having said all that, I am (lucky?!) in that I have hypo awareness and can also tell when my BG is really high (+13 ish) as I start feeling awful. If jess is not like that...ignore me completely!
