Hi Tom, Welcome . I know it seems daunting now but honestly in time it almost becomes second nature.
Many of us here do LCHF ( low carb high fat) don't worry bout the high fat bit, it doesn't mean eating a pound of lard. Its more like not choosing low fat yogurts and using butter , that sort of thing.
Basically our bodies can't handle carbs too well, things like potatoes, bread esp white, pasta and rice are the worst culprits, it's not to say we can't have any, but cutting down and finding substitutes sure does help. Fruit juice though marketed as healthy , is packed full of sugar and many of us need to be careful with fruit, grapes are little sugar bombs, often berries are tolerated better.
We do need to know how food affects us. Wrongly in our opinion most T2s who are not on meds that can cause hypo's, Metformin doesn't, are provided with the very tool that can help us learn what our body tolerates well, diabetes is very individual in this, some people can eat eg porridge others dare not go near it
Many reasons are given ,some of them are dead silly,
The SD Codefree meter is the cheapest one to self fund that we know of, it's test strips are around £8 for 50 other brands strips are between £15 - £25
It's available from Amazon or direct from Homehealth .
We use the mmol/L measurement in the UK and don't forget to claim VAT relief
