Interersting account of an evening! We have a holiday in the USA today so I don't have to work. One thing that might be useful would be to wait longer than 15 minutes to retest. It seemed to be going up although maybe not as fast as you'd hoped. Particularly in the middle of the night, I think that digestion slows and that it takes longer for stuff to hit? The sandwich probably wasn't a bad idea either, although it might be too much, depending on the other variables involved. In that situation I'll sometimes hedge my bets by eating AND bolusing more although this, of course, can lead to going up and down and up and down a couple more times. Yuck.
Re the blog question, I think that's fine, lots of people post links to blogs and videos that can generate discussion. Some people have suggested "why not just post the blog here?" or "I don't click on links to read blogs" so you may lose some readers here but, if you have other readers elsewhere, who don't "Tu", you'd perhaps lose them by posting on Tu. I usually hang out more in the Forum as it seems as if there's more traffic, more discussion which creates, perhaps, more synthesis.
