wow... well i wont even think about using it, like i said. dry ice was a recommendation, not a must. and i now know my husband's insulin does not need to be cooled. so i am comfortable with this outcome...
we use dry ice all the time here... tempatures reach well over 100 degree's. In a small room i even feel safe with dry ice... Honestly. i dont touch it, but it never took my breath away.
