That was me yesterday morning - was hypo from around 3am to 5am, alarm had been going on both phone and pump but I didn't hear it till around 5am as was in a deep sleep, finally woke and was shaking and sweating profusely but managed to swallow 3 glucotabs, fell straight back to sleep and then another low alarm at 6am, felt like I hadn't slept yesterday.. It was odd as I haven't had a night time hypo in over a year, Tandem normally resolves the low, just go easy today and try not to do anything too taxing, take care x
