The temptation to take back more is huge due to the low cost in Bulgaria, but they are quite strict in Bulgaria and many suitcases are scanned for the very purpose of locating fags.
I'm sure they are. I quit on boxing day 2002, after having smoked for 6 years, by will power alone. I can therefore confirm that you do not need patches to give up - discipline and motivation will get you off the "smoke".
