@SuperPB ...I have to l agree with
@OrsonKartt
..."The main thing with it is to make sure you are going in the right direction and keeping there rather than pin point accuracy though... "....
I use the codefree...was explained as better because of strips cost, ( machines a one off cost, the ongoing pain is buying the strips.)
It's not the most accurate, according to a few, but as I'm not going to be auditioning for "Quincy".

..it does for me.
i think it's really about understanding WHERE you are at any time, and spotting any trends.
So it gives me a starting FBG each morning..a start fig BEFORE a meal and a 2 hour fig after.
it doesn't vary wildly from day to day...so if it's out by any degree, it'll be out tomorrow by the same.
what you want is to see trends and how the foods we eat impact on our BG levels.
Depending where you are on the journey,Yours may vary considerably from others.
That
MAY be down to ...
*What your HBA1c was at diagnosis,
*How long you had been diabetic before finding out,
*How disciplined you are re intake of carbs
AND then it's down to your own personal biology.
( diabetes, i think it's latin for "greased pig" ..
because it's so hard to get a real grip on the numbers, some days.)
I've found from the limited time i've been on here, that we may all suffer the same disease...
BUT our treatments, remedies & reactions to each step vary considerably.
Like i say.. the meter is a god send..IF you use it properly.
BUT all it will tell you is the bare figures
THAT'S where the thinking comes in..
As in finding out and identifying what has got it high, and thinking of ways to limit THAT elements impact..
If it helps, most days my FBG is in and around the mid 5's..and up towards the low 6's
most meal times start around the high 5/low 6 marker...and 2 hours on are usually in and around the low 7's
so the scores are pretty constant ..(rarely surprise by a figure as most times i'll be aware if it should be high by my foods/eating times and sometimes simply by how i'm feeling.
I low carb and high fat, but not in the extreme..
I perhaps have 2 meals a day, i aim for 30g carbs a meal, several days of the week that 2nd meal is more of a a large snack ..so i'd say on the week i do 50g carbs a day.
i consciously try to eat within a certain window..(work does impact a tad on that)
i rarely eat a meal before 11 am..and rarely eat after 9pm.
i exercise, when i find time..and gym is once MAYBE twice a week for an hour or so
i jog indoors, sometimes run outside, but more recently now have my old weights bench out, and use the bars and weights most days..say 20/30 mins exercise per day.
i do hear your plea for a fast fix.
i don't know the answer, but for me, when i found out..it was to cut down the carbs.
i've taken apple cider vinegar without any issues (quite like it)..but i can't say it made the numbers tumble, but it hasn't made them worse.
so no..no fast fix sadly.
