keep asking if there is something you are in doubt of..
it is so bas at the beginning, but there is also something you need to learn , first thing is and remains being the food choice, they do not tell you that enough at the GP or hospital, actually they recomend much more carbs on a daily basis than diabetics in general can cope with..
there is some welcome information that everyone new here gets, so I´ll tag
@daisy1 so you´ll get all the information too
if you want to get your blood glucose down fast then take a few days on NO carbs :
which mean eat things like meat (with the fat) nuts like walnuts and brazil-nuts and macadamia nuts, eggs and bacon and
pork scratchings ...
only drink water and totally sugarfree things to drink...
you can drink coffee or tea with fullfat cream if any carbs then eat those that is alreasdy in the food like cucumber tomatoes and avocado.
no bread and no potatoes and no rice no sugar no cakes.....
if you do miss bread too much then buy the famous LIDL protein rolls that have very few carbs in them...
there are treats one can eat that contain hardly any carbs but you cant learn all at the first days
