I am new also.. Less than a year mine is from pancriatitous. Type 1
my level was 600 when I borrowed a meter and had been off all carbs for a week. And I felt like crap...
With levels of 300 I felt okay.
Until I lowered my level. Now I feel good at 90 to 200.
The other issue is I cant tell high from low, I feel the same either way sometimes. Only time I know is if I get hot, sweaty and shaking then its lower than 50, but I dont trust myself and I always check.
Also I was scared to go to low. Under 70 so I keeped the levels high.
I talked to a guy thats on a pump for a long time and he helped me allot.
Until I talked to him I felt it was silly to to seek someone else like a support group but it does help. As you get used to being diabetic you get laxed and slip from good habits.
I guess what I saying in short is you will fell good at your average over time. Your body has to adapt. But your body will not adapt to the long term issues high levels will have on your organs.
