Actually, onehand, you don't need to carry a flaming 'purse' full of kit around.
I don't use a pen injector, just a disposable syringe.
I don't need a meter, normally. I mostly use visually read strips (which I cut with scissors into striplets): Glucoflex-R or Betachek Visual. They both come in a very small pot. (And I don't use any nasty spring-loaded gadget to get the blood, just a bare lancet - which I use again and again.)
In an even smaller pot, I carry some jelly beans.
However, most important for me during the day is rye bread (with pear and apple spread): if I go out, I take it with me. By eating rye bread steadily during the day, hypos are far less of a threat. (It's slowly digested, so a dribble of glucose is constantly entering the bloodstream.) But I don't eat any after 3.00pm, or my blood sugar would rise later in the evening and overnight.
It's my diet that allows me to safely keep my blood sugar near normal all of the time.(My last HbA1c was 26mmol/mol.)
And 'feeding' the insulin allows me to ensure that, at bedtime, the insulin I took earlier is exhausted. (See some of my recent postings.) So I sleep safe.
Let me repeat: eat well, and dump the needless junk.
Reverse reverse-Luddism now!
