A field of Frilled Anemone.
DAN (Divers Alert Network) also has a protocol for diabetics on insulin to dive safely.
Thanks Joan, and welcome to the group !
Thanks Mario. I just got back from a month's diving in Bonaire. I agree ... Just keep testing, watch the trends and carry fast acting carbs. I find that the honey Stingers work best for me. No need to give up diving!
