Debs, I think you a placing far too much emphasis on your fasting blood glucose as a marker. I would advise you to stop taking it for a few weeks. Instead, pick another measure, say your pre-evening meal bg, and track that for a while instead. Here's why:
Fasting bg is affected by a heck of a lot more than yesterday's eating. Stress, pain, disturbed sleep, hormone rises and imbalances... None of those are under your control, and trying to spot a correlation between just diet and bg when all those other factors are going on is hopeless and just adding to your stress. And if you are someone like me, whose DP is affected primarily by cortisol (stress), then you are never going to get the results you want by using bg as your method of management.
By switching to (for example) your pre-dinner bg measurement as your daily 'marker' you could learn a lot. By late afternoon/early evening, you will probably see your lowest bg figure of the day. Those morning stress hormones are long gone, insulin resistance tends to drop over the day too. Hopefully it would give you a reliable and more consistent 'baseline'.
Personally, I used to see high 5s Before dinner (after 2 years of vlc and a fair bit of physiological insulin resistance). When I started 16/8 IF, I saw no change. When I started 24hr IF, my pre-dinner numbers dropped to the low 5s. When I gave up coffee I started seeing 4s for the first time in 3 years. I now consistently see 4s every day at that time, sometimes low 4s, even on non-fasting days. During the same period, my fasting bg has bounced around the 6s, 7s, and occasional low 5s and 8s with no pattern or consistency, although giving up coffee has lowered it a bit.
Give the pre-dinner reading a go, it may set your mind at rest, which is better than worriting about something (fbg) which is largely out of your ability to control.
