Body rejecting cigarettes, normal?

I had a bad migraine a week ago and a cigarette sparked it’s start

Ever since, I have reduced smoking by 90%, maybe 3-4 a day now without inhaling.. but every time I smoke I feel horrible, like accentuated pins and needles or numbness in random parts of the body, numb lips, bloated stomach, I become very irritable

Like this may sound stupid but I get withdrawal effects WHEN I smoke, and when I don’t smoke I feel great bar the mild brain fog and lack of concentration

I’ve bene smoking for 15 years, stopped only 2-3 times for 3-4 months in this time, wanna quit for good, but just curious and confused what is happening this time around..
