I had it with my first pregnancy, but I delivered early so I wasn't on the diet too long (preterm labor believed to be related to carrying twins and not to the diabetes). This time around they tested me at twelve weeks due to history of diabetes with previous pregnancy. I've been on the diet for twelve weeks, and they recently started me on glyburide to stimulate my pancreas to create more insulin. I'm guessing they may increase that from once a day to twice a day at some point, as my lunch sugar levels still seem to be at or above the limit most days. I give you my background so that you'll have a better idea of if you want to ask me anything.
A couple of things that I've found helpful: Each time I finish a meal, I set the alarm on my phone. Otherwise, I find it very difficult to keep track of when to test my sugar. I also keep some alcohol wipes in my kit for times when I am nowhere near a place to wash my hands. I searched the web for low carb recipes, but I also continue to make well-balanced "meat, veggie, carb" dinners most of the time. McDonald's snack wraps are a nice low/medium carb option when we're out and about. I like the granola bites made by Archer Farms (found them at Target) for when I can only afford to eat one carb. I also keep a stash of nuts on hand for when I need some crunch.
This message got a lot longer than I intended, so I'm gonna stop now. If you have more questions, please don't hesitate to ask...
