After a long stint in hospital, my blood sugar control went haywire, even when I returned to the low carb regime which had worked previously. Also, I was sleeping poorly, waking up several times and unable to get back to sleep. So I began taking a modest magnesium supplement (375 mg). My BG went down, in fact sharply at night. My CGM was recording hypos almost every night, one lasting 3 hours, and in the times they woke me up, I felt unwell - very woozy. At first I didn't connect it with the magnesium supplement, but after 2 weeks of it worsening, it occurred to me, and I stopped it. Et voilà! My BG began to go up, out of control again, with highs lasting a long time after a low carb meal. No more night time hypos, but also poorer sleep. I don't want to consult my GP, who will just increase my medication, and anyway, I've been relegated to the pharmacist and a request for a brief meeting with an assistant. So any suggestions?
