Something is definitely wrong. Smoking corrodes your body and makes your inner stomach lining corrode. Nicotine is hard to get off of. But as a smoker all I can ask you to do is, stop before it gets worse.

You should stop smoking and find a substitute for it.
Like if you are smoking due to anxiety then you should do some physical workout and stuff may be join a gym.
Consult a psychiatrist he will give you medicine so that you can get rid of it.
