Joined an unwelcome but not unexpected club this week

#1 thing to know is-

Everyone potentially reacts differently to any control methods, so what works for me may not work for you.

For me, the first and second things I did on day one were-

1- Switch to diet soda. I realize it's also full of highly refined chemicals.
...but regular soda @ 200 cal per 8 oz puts me to 300 hg/dcl in 15 minutes.
Diet soda does not change my number at all.

2- Eliminate all "stand alone" bread. No biscuits unless it has meat on it and is the main course of thee meal. No bread sticks, no slice of bread just because.

Just doing those 2 things brought my A1c from 14 to 10.

The next thing I did was move meal times up.
Breakfast- 5:00 am
Lunch- 10:30/11:30
Dinner- no later than 6:30 (5:00 preferred), and for every hour past 5:00, subtract carbs, IE
5:00, burger is fine. 7:00 (hey, it happens), get the salmon, with a vegetable.

Likely the next best thing- No pizza for dinner and for God's sake no pizza after 7:00 pm EVER.

Doing that and a few other things has me between 6.7 and 7.1 on a regular basis.

I've found I can eat anything I want as long as I do it rationally.
Donut? Fine- early, so it can be burned off.
