Hi Domforr
I agree with all of the above. Since diagnosis three and a half years, I've kept a record of BG fasting and two hours after and what I've eaten, I've found it invaluable as I can highlight what food does to my BG. I aim for between 60-90 g carb a day which includes one slice of bread and loads of butter plus a scape of sugar free home made marmalade (basically an orange and leaf gelatine) and I keep bread in the freezer so it's hard to get at, toast from frozen but as you have to wait for it to defrost I don't turn it into a sandwich.
Keeping a record is very handy when you see your GP or medical people. The other thing to watch is does your meter need new batteries and can you check that it's accurate? At my annual review I always take it and check it with the surgery one, just one prick, two testing strips one for each machine gives you a good idea if yours is working or not.
Stress and infection are two huge challenges to BG mine always rises 2 -6 more when my rheumatoid arthritis flares up or when I've a cold or virus, but I can put this on the record so I'm not completely freaked out.
Hope some of what's been said helps, let us know how you get on.
