I'm on a pump since June of this year. Was MDI'ing for the last 20 odd years.
I'm also 10 weeks pregnant with my second baby. When I was pregnant the first time I have a DREADFUL time with hypos. I would go hypo about 2.5 hours post meal. My sugars would be on target 2 hours post food, but I would drop like a stone after that unless I had huge snacks at exactly 2 hours.
Since I have become pregnant this time I ONLY dual wave. Usually 40%/60% and over 1-2 hours depending on what I am eating (fat content, volume etc).
Its a dream. My sugars are constant, predictable, I don't spike as badly and most importantly - I'm not getting those crippling lows.
Dual wave for President :0)
