I used to rely on peanut butter crackers, cheese crackers, banana…..but kept juice as my staple for treating lows. I recently bought some sugar gel tabs, I’ve also used small tubes of cake icing. You can pack the snacks into a bag with diabetes supplies and it shouldn’t be counted against you as a bag, since it’s medical. I’d have a doctor note ready, but I’ve never been required to produce it. Also, had a prescription for my supplies.

Do you wear a CGM? Or insulin pump? My Medtronic 780 is what keeps me away from lows pretty well. The use of a cgm should help prevent lows, though I still do fingersticks and carry a sugar source with me at all times.
