I quit smoking for almost 4 months now. I am a diabetic and ever since I quit smoking my blood sugars have been elevated, between 200-300. THe MD has mad adjustments to my insulin with insulin coverage, but they remain high, My speech is slurred at times, my body feels numb, and I have a lot of nausea. My menstrual period did not arrive at the time it should have a week ago and still hasn t arrived. I am very regular, basically I just feel awful.
