It depends on the circumstances. You know what kills me? I had this "nurse" 'friend' who had the gall to ask me if I should be checking so often. What a hag. I have had one other person ask me that as well.
Nowadays, well...I'll tell you, I struggle some days. 4x a day is better than some days for me. I think I get off with checking because of sleep or something. I've been at this disease for a while, and I am making strides in my own way.
Do you group your checks? I just realized that I do that...major checks are the automatic timed/schedules ones, like after I get up, etc. Minor checks seem to be quicker somehow and include before driving, which can also be a major check, as well as the I-feel-lousy checks. Anyway. I don't know how often I check...I think I am extremely disorganized and my memory is partitioned mostly for work, so I tend to not even know. I'll think I haven't checked at all and look at the BG screen on my pump and see that I did, which is weird.
I would like to try out a CGM, desperately...it seems like such as blessing (ignorance is bliss, I guess). It would be nice, I imagine, to know. I had this wrist version of one, but it never seemed to function properly.
