Indeed lh378, as I've said before, Bernstein is a phenomenal doctor, but a horrible chef. Through your own trial and error, and regular validation with your meter, you will find the right low-carb diet for you that is both delicious, suits your metabolism and meets your BG targets.
Bernstein is an MD so it is a good thing that he is a competent doctor first and foremost I'd be satisfied to have a competent, caring doctor with good common sense who is a horrible chef than a doctor who cares more about _ (fill it in with whatever you wish, their next vacation, summer home, yacht...etc) than his patients. His laws of small numbers kept me calm when I experienced the 60 at night. If the Lantus were behaving as a fast acting insulin because the microcrystals released all the insulin, I was basically facing 4 units of bolus instead of 4 units of basal. The science and technology of the microcrystals and the slow dissolution of Lantus is fascinating. However, given the potential deadly consequences of the "fail"- why would anyone still wish to use Lantus? at a low dose of 4 units not so bad. What if one were using 40 units of Lantus and all of the insulin became fast? I'm considering switching to Levemir. (I plan to go on the pod some time in the future, but one step at a time)
Like everything else with diabetes, finding the right insulin is a matter of trial and error. I started with with a single 24hr dose of Lantus and ended up switching to two 12hr doses of Levemir which I found to give me much better basal control. It's hands down my favorite insulin. So much so that I actually prefer MDI to my Omnipod. I only use my Omnipod when I travel due to the convenience and discretion it provides. When at home, its Levemir and Humalog or Novolog.
It seems like you wound up with too much insulin for some reason, probably injecting the lantus into a small vein or something and maybe your pancreas added some too because you're in the honeymoon.
In cases like that and for my bad lows I always give as much sugar as I feel I need and I don't care about spikes, a bad low is much worse than any spike treating it may cause or any roller coaster because it can kill you.
At 50 bg, not really a moderate low, your body will start to react by producing glucagon/glycogen to try to raise bg, over time this fails in people with type 1 and type 2 with little or no beta cell function left. Also at 50 bg you can have seizures, most people don't seem to but it does happen- someone on another forum who has longer term type 1 of several years said she had a seizure at 50 bg.
Another possible bad effect of allowing lows to go to 50 is you can have a glucagon/glycogen rebound which combines with your treatment of the low.
The way I try to deal with my lows is to stop them before they ever get to the 50's now by treating conservatively for me most of the time.
But there are times I can feel I'm dropping really fast and then I drink juice/glucose drinks etc.
About 3 weeks ago I started crashing right after dinner - I drank 2 glasses OJ and had 2-4 glucose tabs around 80g and there was NO spike even with my dinner included so that was a bad and dangerous low. I believe what happened was a tad too much activity and constipation stopped the food from getting into me- my bolus was appropriate for what I ate and my activity etc. and there were no mistakes made. I don't think I even pre bolused for that meal, not more than 5 minutes at most, so now I don't usually prebolus at all unless my bg is higher.
At night I often have some flax seeds/chia seeds and almond milk now(advice of my CDE- Who also gave me some good low carb diet regimens to look at) to help with dp and to stay more stable and not drop too low. It is difficult because I go low at night(or when I sleep) and I also have DP, so managing both isn't easy.
