Oh sorry to hear he's been eating your glucose tabs
Can you hide them or something? Maybe keep them in your handbag or a locked drawer/cupboard? I'm not sure how you can get him to stop eating them? My friend tells me her hubby steals her hypo treatments as well. She said she just keeps a mix of everything right around the house (juice, tabs, sweets, etc). She said she's had to resort to dissolving sugar in water recently though because her hubby finds everything and ate her supply. He apparently promises to replace it but she always has to do that. At least he doesn't steal her batteries for her pump she says. Maybe you could ask your hubby to report what he has eaten of your supply so that way you know what needs replacing? I would hope he realises how serious it is that he needs to help you keep your stash available. I wish you the best.
