I got that - so I gave up.That feeling was so unpleasant.Been off them for 3 yrs now.Good Luck if you bite the bullet - you could do it you know if you wanted.
The only time I have ever experienced this sensation in all my years of smoking was when I first started smoking, or if I had not smoked for quite some time, and I attributed it to the "nicotine rush". If neither of these circumstances apply, then maybe it is time for you to quit, or at least see a doctor about it
