Poll: What BG levels can you autodetect and feel diabetes issues at?

So, my diabetes nurses seem to think I should only worry if my BG readings are above 140 and yet I feel symptoms/issues at lower levels — in the spirit of all the other recent polls, I thought I’d ask at what point everyone really notices they have high BG and need to take steps to correct (even w/o looking at a meter.)

For me, my cognitive ability really seems to suffer when I am above 120 for any sustained period. I can usually tell that I’ve reached 120 within 20 minutes or so.

Also, the moment I go over 130, I tend to immediately have one or a combination of tingling/headaches/tiredness/frequent urination/etc. I honestly can’t stand ever going over 130 now.

I’ve only been a diabetic for 6 months, so this all freaks me out and I’m doing what I can to stay under 130 at all times (noted in another topic).

I’m really curious at what BG levels others really notice issues….
