Why cant I get to sleep at night and why do I wake up in the night?
Insomnia can be caused by too much adrenaline in your body. Whether this is because you are feeling stressed, or whether it is because you have rocky blood sugar levels, or both. Waking up in the middle of the night is for the same reason, you will have had a drop in blood sugar and your stress hormones would have been at work pouring out adrenaline in an attempt to balance your blood sugar level. There are two stages to this if you wake up and cant go back to sleep without eating something (usually carbohydrate like a bowl of cereal), then you are experiencing a blood sugar drop. If you have slept through that but wake up feeling irritable or worried, the stress hormones have already responded and are rushing around your body trying to get the blood sugar level balanced again. Either way, a blood sugar drop in the night can mean that you dont sleep well (you may sleep through it), but you will find it hard to wake up in the morning and you wont feel hungry or want to eat anything stra
