| I've been through these long stretches...they often creep up and you wonder how in the world you can be so far off track...even after covering all carbs and testing regularly.
I went to Europe last year and ran extremely high every night...but would be very low while sightseeing each day. My basal seemed to be on US time...add the pasta to the situation, it took a lot of nights of getting up and testing to see if I was high...was almost every night...in the 200's & 300's. I would give myself a nighttime bolus (hate to do) and wake up the same.
It took weeks for me to get back to normal. Whatever normal is for a Type I. I think my body was really resistant due to jet lag, big meals every night & such.
I changed my insulin (have you tried opening new vials/cartridges?)...everything. After I ramped up the basal, then I started running too low at night & before meals.
Go figure. Add PMS to the picture...it just was crazy.
Now, I have little stretches like this...but, just to let you know it happens to most of us...at some point in time. This disease is called the "sneaky disease" for many reasons. It would be nice if our metabolism would cooperate every now & then!  |
