The insulin triggers are slow to turn off after the extra blood sugar is broken down thus, it also consumes the normal
blood sugars dropping its levels. This is common
in pre-
diabetics as well as some other conditions. It is usually controlled with a change in eating habits (only high protein/fat food at night, no carbs after 6 PM) and often Chromium picolinate, a metabolic and blood sugar regulator, is recommended.
