I too wake up overnight with really low blood sugars. Sometimes too weak or nausous in the morning to get up. I eat a 100-150 calorie snack at bed time that is a carbohydrate and it has helped tremendously. Keep something very sugary close by if it still happens, but follow up with a complex carb so it doesn't crash again. :-)
It is possible that you need your medication dose changed. You really should check with your physician. The best is oj with teaspoon of sugar for immediate help though. Good luck.
These pranayam exercises will help control the diabetes and the side effects and also overcome the allergies.Build up the timing gradually.If you feel tired or dizzy, stop and resume later(after about a minute).The benefits will be noticed in weeks as the sugar level is checked daily.Over the long term the diabetes will be in full control and the medicine can be reduced in consultation with the doctor.
Kapalbhati -(Do it before eating) Push air forcefully out through the nose about once per second. Stomach will itself go in(contract in). The breathing in(through the nose) will happen automatically. Establish a rhythm and do for 20 to 30 minutes twice a day.(Max 60 min/day)
Children under 15 years – do 5 to 10 minutes twice a day.
Not for pregnant women. Seriously ill people do it gently.
Anulom Vilom –
Close your right nostril with thumb and deep breath-in through left nostril
then – close left nostril with two fingers and breath-out through right nostril
then -keeping the left nostril closed deep breath-in through right nostril
then - close your right nostril with thumb and breath-out through left nostril.
This is one cycle of anulom vilom.
Repeat this cycle for 20 to 30 minutes twice a day(maximum 60 minutes in one day).
Children under 15 years - do 5 to 10 minutes twice a day.
You can do this before breakfast/lunch/dinner or before bedtime or in bed.Remember to take deep long breaths into the lungs.You can do this while sitting on floor or chair or lying in bed.
Also everyday, press the centre point of the palm of both your hands 40 times with the thumb and press the tips of all fingers 40 times each.
Also do this: kneel down, breathe out,pull in stomach, keep your both hands on stomach, bend forward and try to touch the floor with your forehead.Do this 3 times to stimulate the kidney and pancreas.
Continue the exercises once a day, after the diabetes is in full control.
Remember it is the timing and duration of pranayam which really gets the body to fight health problems.Start with an open mind, and come back to report your progress.
