My last endo was similar to yours, I think–constantly criticizing me about my lows when I didn’t think they were much of a problem (except the ones I’d occasionally get at night). I didn’t actually switch endos for this reason, but I’m much happier with my current endo, who places a higher value on my opinion about what’s interfering with my life and what’s not. I rarely have lows below 50 mg/dL, and that’s good enough for me (and also not so dangerous, from a medical point of view). I also don’t have lows at night anymore (and I can prove this with my new Dexcom!) But I probably do have a couple episodes a week of lows in the 55-65 range.
So basically, I think you should find another endo who’ll respect your opinions about your treatment more and possibly help educate you about how to adjust your own insulin doses. (Or you may need to see a CDE for this, depending on how the practice works.)
I’ve also battled the yeastie beasties much in the past. The only piece of standard advice that I follow that hasn’t been mentioned here yet is sleeping without underwear (and in loose clothing, of course). By being pretty obsessive about the hygiene-related stuff and improving my BG control, I’ve eliminated the recurrent yeasties, but every few months or so I’ll get one again. Usually the yeastie will happen after my period, when I’ve been having to wear underwear at night with a pantyliner for backup (I use a menstrual cup instead of tampons or pads, which is a whole nother discussion…) I swear by the 7-day OTC yeast infection treatments because I feel like the longer, more spread-out treatment has a better chance of eliminating all the beasties. I was told by my gyno to avoid the 1-day treatments, so I never do those (I sometimes use the 3-day treatments if I know my week is going to be busy or I’m traveling or whatnot). I know a lot of women who will call in to their gyno for an oral anti-fugal Rx when they get a yeastie instead of taking an OTC remedy. These are often more expensive (with my insurance co-pay) than an OTC kit, so that’s why I don’t do this. Not sure if they’re more effective or not, as I’ve only taken one once.
(Also, one last thing. Another tip (beside the yogurt tip, which I have no opinion on) that often floats around the interwebs is the peeled glove of garlic up your va-jay-jay thing. I recommend against this. Yes, I tried it in my days of desperation! It didn’t work, and it makes you taste garlic for days…as soon as you put the garlic in, there is some magical mucuous membrane connection to your taste buds…if you don’t believe me, try it, but beware of the consequences!)
