You eat or drink excess Sugar (the average American consumes well over 100 lbs/yr.).
The body releases insulin to put Sugar into storage, but the insulin response is excessive (due to ADAPTATION and/or chromium deficiency).
About 2 hours later so much sugar has been put into storage that there is not enough left in the blood, and you get a low-blood-sugar emergency.
Symptoms such as weakness and mental fog begin.
The body responds to the emergency by dumping adrenaline into the system.
More symptoms follow from the high adrenaline, such as racing heart, anxiety, etc., etc., etc..
The roller coaster rises and falls in critical hormones, causing an unbalance in all the hormones and often resulting in ongoing symptoms.
And on symptoms of hypoglycemia:
Many Americans have hypoglycemia to a greater or less degree. The symptoms comprise a remarkably long list and range from mild discomfort to being completely incapacitated.
Mental Symptoms
Anxiety - ranging from constant worry to panic attacks.
Phobias - claustrophobia, agoraphobia, acrophobia, and so on. This is anxiety tied to a particular issue.
Forgetfulness - this may just be choline/inositol deficiency.
Inability to concentrate
Unsocial, Asocial, Anti-Social behavior
Crying spells
Nightmares & night terrors - terror can continue after you wake up. It is especially indicative of hypoglycemia if you wake in a cold sweat, if the terror continues, if there is pressure on the chest, or if you are unable to breathe.
Physical Symptoms
Headaches - especially if a meal is missed.
Tachycardia - racing pulse due to high adrenaline.
Fatigue, weakness, "rubbery" legs.
Tremor or trembling of arm, leg, or whole body (outside or inside)
Twitching, jerking, or cramping of a leg muscle - cramping may be just calcium or magnesium deficiency or food allergy response.
Waking after 2-3 hrs sleep
Tinnitus - ringing in the ear, due to high insulin in about 70 % of tinnitus cases.
Abnormal weight - too high or too low.
Compulsive craving for sweets, colas, coffee, alcohol
