Hi Columbiana7263,
I too can relate to the roller coaster ride - mostly triggered by Low Blood Glucose Levels. It happens usually when something unexpected happens. Just the other day we were late having dinner because my daughter called. She had just got back from one of her deployments with the navy and gave us a call. My spouse took the call and it didn't take me long to figure out it was my daughter - but my BG levels were getting low (2.8) so I told my spouse and them my son to talk to her first while I frantically downed a sugary drink to get my BG levels back up.
As you probably already know, it's easy to over-compensate. I got on the phone still feeling low but alive. We had a good talk and as I got off the phone I tested myself again and this time I was at 14.5 - quite a difference from the 2.8 that I had tested before downing the pop - so I gave myself another shot to get it back down.
That's a typical roller coaster event for me. Having spoken to other type 1s this seems to be a common challenge. When your really low it's like your survival instincts kick in and you start eating - compensating for the lows but it's difficult to stop eating thus causing your blood sugar levels to go too high (from a low).I've been living with type 1 for 50 years and I still haven't been able to compensate without hitting a high. I do a better job of it now but it takes a lot of discipline.
I find Blood Glucose levels also influence ones mental health or disposition. When I hit a certain blood sugar range I'll get really grumpy. I'm lucky to have friends and family that will recognize this and provide understanding and support.
