cigarettes?

why do you get light-headed(dizzy) if you smoke a cigarette after not smoking for couple of days? the effect of the nictine and other chemicals reduce the amount of oxygen getting to your brain, on a normal time of continuous smoking you dont notice the deficiency of oxygen. but after a couple of days off the smokes you capture used to normal amount of oxygen and the reduced amount from the ciggarette sort of make you pass out surrounded by a really mild sort of way
because your making the withdrawls stop
possibly
it cause the small veins to shrink at extremities of body smaller the vein more closed completely
It is from the nicotine in the cigarette:
Nicotine is a powerful drug. What you are doing is getting dignified off the nicotine within the cigarette.
beacuse u weren't used to it for a while, then started again, so u get sick once more.?
Its of late the nicotene losing its effect. Its a good sign, which funds that your body is going through a cleaning service. All the drugs are removed and you feel close to a new being. Instead of stop smoking for a couple of days, make it forever. I know its difficult but oodles were competent to escape that habit.
