hi bro,
i saw all the replies u've got regarding ur question but no one was near satisfaction, lol. i'm in the same boat of urs. go to hamad hospital in the outpatient dept, they will give u the appointment in the anti smoking unit, u'll go through an interview with the doctor and when the course will start and if it will suit u, for sure u'll quit smoking maximum in a period of three months. i got this info from a friend of mine who is also a doctor in hamad hospital. i'm about to go for this but my problem is time. i wish u good luck,
regards
khalid
