I second the "check with the doc" bit. Tell them what you've learned here, and ask what they recommend. They know exactly what they did and what they expect and when.

I've seen more than my share of hypoglycemic disasters, and that's what I'm thinking about right now. There are other issues, too. Your doc is really your best reference at this point. Print up this thread and take it in to the doc and get his/her take on it.
