my go to hypo treatment is apple & blackcurrant juice boxes. I keep them everywhere and it's the only juice box I can handle (well not totally, but it helps). I also keep soft lollies of some sort at home and in my bag as well. But I find juice works a lot quicker for me and I don't have to worry about choking (my throat doesn't move well and I can choke on stuff easily). If you can't find anything at home you can use dissolved sugar in water, or honey.
