Hi I'm in the u.k.
I've had type 1 for fifty years now and gave always been a brittle type never able to control highs and lows.
Now I'm finding that my humulin s is hardly working when I take it an hour before my meal.
I was told by diabetic nurse that because I have hashi underactive it affects the blood sugar control.
I wasn't given any more advice at all.
Are there any others that have have similar? Please share.
