I recall when I quit smoking some 3 years ago , I used to feel light headedness. When I walk , it used to feel I am totally disoriented. The doc told me that due to the 'cold turkey ' quitting which I did, the BP dropped and my body was making adjustments. I used to feel very drowsy and lethargic.
Your blood pressure doesn't get higher when you quit, even if you stress out about not giving in to your habit, still the vascular constriction caused by having nicotine and carbon monoxide in the bloodstream cause far higher blood pressure than even the childish stress of not giving in to the ba<x>se impulse. Quitting smoking alone reduces the odds of a heart attack or stroke by 50%
