Whether cessation of smoking can evoke corpulence ?
No, if one does it with help of IAPS, so it will NOT evoke.
The IAPS's methods returns a smoker (narcoman in general) to the state, which he had BEFORE he/she began to smoke. If then he hadn't inclination to the corpulence, so it will not arise after cessation of smoking.
And if the inclination existed, so it may become a separate theme of help to the patient.
