I haven't had a cigarette in almost two weeks now, but my arms and legs feel numb and weak. I can still function properly but feel blurry and almost like an out of body feeling. It's a weird and an uneasy feeling. How long does the fatigue and weakness usually last. I was a light smoker, like 3-5 a day and have only smoked for 3 years. But I've noticed the anxiety and panic attacks have lessened since I quit. Still, the weakness in my legs and arms is bothering me. Any answers for this?
