I totally “get” the idea of aiming for a difficult target rather than being lazy or accepting mediocrity. I just wouldn’t want someone to become discouraged if they can’t hit a target like that. I also am of the school of thought that overly tight control is actually counter-productive. There are scientific studies that support that idea, though it is far from a universal truth.
Anyway, I read your use of the phrase “argue with my doc” and maybe read too much into that; if that’s the case then you can disregard the second half of what I wrote 
However, I definitely think that a good endo knows a lot of things about this disease that most of us as patients do not fully grasp. Similarly, there are things about this disease, things that are learned by living with it rather than just studying and treating it, that most endos won’t really know. Good, effective diabetes treatment has to be a two-way street, for sure.
Have you tried an extended bolus?
I wiould like to clarify and comment again on the comments I made earlier, I am very sorry if I offeened anyone by calling myself the “anti chirst” when talking about just relaxing and enjoying life - but, I just wasnt to say, I myself did focus ALL MY ENERGY on gettingmy 1 hour post meal bgs to 120 and I had a STROKE. I do, truly, believe this was because of the stress created by believing that this attention would extend my life, which was,to be certain,MISERABLE. When I becoame “lazy” and decieded that the stress of achieving a perfect A1C and not the 5.8 that I was achieving at the time, I became happiier, "lazy"maybe,we all need to make that decision. I was a very succesful businessman with an A!C of 5.8, so I didnt consider myself at all “lazy” and any diabetic out there who is payuing attention to bg’s all day and working a full time job whisle exercising 3 to 4 times a wek might l be a bit offended by the implication that they are being “Lazy”. In any case, I decided to enjoy life AND focus on an A1C of 6.5, as it is now, yes, I want to be attentive and still do what we are all reallly here for, enjoying life. I’d rather live, love, laugh and RELAX and, guess what? I’ll bet I live LONGER as a result vs. going crazy over my bg’s and dying even earlier than this insidious condition is going to kill me in the first place. If any of this makes any sense to you, maybe check ot my site www.supportersofsurvivors.com, and check out my book/essay on the subject. Agein, I apologize to anyone who is offended by my strong position! We all have to make our own decisions, for sure!
