So have I.  It killed my mother.

Even though she was on insulin, she did not have the discipline necessary for it to have any real chance of control - it merely delayed the inevitable.  After years of food abuse, the effects hit hard ... and quickly.  Over the last couple of weeks, the speed of decline was frightening.

Since upping the daily shot from 10 units to 15 units my fasting blood sugar has come down dramatically. Tuesday was 120mg/dL. Yesterday 113mg/dL. This morning 109mg/dL. For a non-diabetic should ideally be 100mg/dL or less. But anything under 120mg/dL is considered "acceptable". So I'm getting there.  :-+

Good news.

A word of caution if I may, and I'll add that you've said nothing to make me suspect you're doing this, so treat this as a public service announcement and not directed at you. A doctor I was talking to once said that it was "Important to remember to treat the patient or disease, not treat the numbers". With any physiological process that can spit out numbers ostensibly characterising how 'good' or 'bad' things are there's a tendency for both doctors and patients (also public health authorities and policy makers) to fixate on the numbers, sometimes to the detriment of the person/people being treated.

In a perfectly healthy individual you can expect the numbers to bounce around from day to day and it's important to remember that you're measuring a noisy process, with the analytical equivalent of 2 or 3 digit DVM, and also that the 'normal' figures are derived from population norms that are themselves noisy and sometimes from such small sample sizes that it'd be embarrassing to be caught relying on them. Thus the practical difference between 109mg/dL and 'normal' is a bit like the practical difference between 5.25V on a rail and the nominal 5V figure. Sure, if you've got a handy adjustment and an accurate enough meter you'd probably adjust that rail to 5.00V but you don't actually have to. As long as the device is working well 5.25V is fine, and similarly with disease processes that have 'numbers', as long as the patient is healthy that's the important thing, not that the 'numbers' are spot on. On the particular subject of diabetes I wonder what effect happens  in the US where 3 digit mg/dL figures are used, versus places that use mmol/L figures that are usually expressed as two digits - that 109 mg/dL would come out as 6.1 mmol/L. Does it predispose people to inappropriate over-precision because there are 3 rather than 2 digits in the number?

With diabetes we're quite lucky that HbA1c figures give a much better picture than regular blood sugar readings, so those are the numbers to pay attention to. Of course with HbA1c being a long term measurement they are much harder to tune in (long phase delay in the control loop). Beware doctors who inappropriately obsess on short term measures of physiology (like instantaneous blood sugar measurements) versus long term ones (like HbA1c) and/or the actual health of their patients. For the avoidance of doubt there are, of course, values of short term measurements that need treating as medical emergencies, it's quite right to react to 'numbers' that are so statistically significantly off the norm that they indicate an immediate or immanent problem.

Indeed. Everytime a new medical professional takes SWMBO's blood pressure they think she is about to keel over because it's so low, but it's perfectly normal for her and she has history to prove it.

Just spent the better part of 2 hours insuring the compensation on all four channels of this Type 1A4 was correct. It is, finally. The one tricky part was the final output to the mainframe high frequency adjustment. 3 trim caps and 3 trim pots to futz with and constantly re-adjust. Couldn't get it exactly as shown in the manual but got it damn close and good enough.

Now to jackass the Type 547 back up and re-claim bench 2. I am done with boat anchors for a while. The next few projects on tap will be much easier to work on.  :phew:


   

med6753:
"Primate Posturing" That's a new one. Is it something like this?  :-//

You may kiss it if you like.  ::)

nixiefreqq:
was hoping to see results from people cutting the tops off of transistor cans and actually using them as phototransistors.

BUT the thread has taken a turn.......to monkeys assholes.

(seem to remember that decapitating 2n404's was a thing maybe 50 years ago.  but could find no details on the interweb)
