For all the bad press that HFCS gets, I've never seen a study that compares the health risks against other types of sugars. I'm not convinced that HFCS is to blame - just high consumption.
That could possibly be true. I can’t be certain. I do avoid HFCS as much as possible now, though every now and then I will drink it in a Barqs rootbeer. I will do this rarely between morning and noon if I feel low blood sugar as a result of my meds.
Eating a light breakfast and then taking the meds can lead to this if I expend too much energy on activities in the morning.
