Welcome, Australia – land of Tim Tams and Tim Winton. (Both, luckily, available in 
and best enjoyed together.)

I have been to Canada, but apparently I don’t speak Canadian. Hmm.

Tim Tams are oh soooo dangerous. I could easily eat an entire package.

Chris just remember to say “anyways” and “eh?” and you’re pretty much a local!!!
Last visit was last Christmas where an Uncle introduced us to the delightful poutine.
Yum!!! Between poutine and Tim Tams, we’re all in trouble!!

Being from Minnesota, I got the “eh” down pat. Poutine is lovely, I have had a few good ones in Montreal, but believe it or not I had my best Poutine in Wisconsin with fried cheese curds.

Welcome @TomH! With enough insulin you can cause a low and then use the Tim Tam’s to recover. Just saying

Easier still, multiply by 20 and reduce by 10%.

So much better than trying to multiply by 18!

I developed T1 55 years ago. At one point in 80s my control via test strips & MDI syringes waned & I sought a new Endocrinologist. Was offered choice of Pump or Pens, chose pens as could not conceive wearing a tubed pump 24x7. 5 years ago, newer PCP enrolled me for Dexcom CGM, got unprecedented insight & better control. Learning Dexcom features online, read about Omnipod tubeless pumps. Convinced my Endo to prescribe, started Omnipod 5 in automated mode Dec 25. Was able to set it up from Online training & videos to approximate my MDI dosages, called OP 24x7 helpful customer support a couple times to clarify settings so I could revise. They are not allowed to offer individual medical advice, but can explain all the settings. The convenience of dosing for meals & snacks is so vastly greater than with pens that I do it more frequently, using smaller doses. Only the background basal dosing every 5 minute interval is automated. Unlike 24hr long insulins, it will diminish/cease as one’s mgdl falls beneath lower bound, resume/increase as it rises.
I gather one can get even closer more aggressive control with DIY combos lacking vendor support, but I am happy with this.

Hi @larry-butler, welcome to FUD and thank you for sharing. You’ve found a great place, and we all look forward to sharing our experiences with you, as well as getting the benefit of yours. May I suggest you hop on over to the “Welcome” thread and introduce yourself so we can give you a proper welcome. Or maybe @ClaudnDaye or one of the others with a higher pay-grade than me can move your introductory post over there, where it is likely to be seen by more members.

OMG!!! My diagnosis BG was 998 mg/dL, which converts to 55.4 mmol/L. Yet another way to be appalled at my own diagnosis story!

Think of a number, double it, remember the result, multiple by 10 and subtract the remembered result. (Or subtract the original number twice, this can be easier.)
Going the other way; divide by 2 then add 1/10th of the result and divide by 10. If you want you can then add 1/100 in addition at the second step to get something which is pretty close to exact (more close than 1/18 I think!)
In practice for forum posts this is more than accurate enough:
mg/dL: just quote the first two digits. Simply divide by 20 (divide by 10 then halve it) to get mmol/L and just quote the first two digits.
mmol/L: just quote the first two digits. Multiple by 10 then double to get mg/dL and just quote the first two digits.
Sometimes it might be good to get more accurate for low BG; “4” is actually about “70”, not “80”, but by “100” “5” should be fine. 5 is 90, not 100.
The point is to make it easier for people who speak the other language to understand a complete post. BG measurements, particularly high and low, aren’t that accurate, at best 10%, and a factor of 20 is 10% bigger than a factor of 18.
