I tried that...
Its torture.
Then the worse is only buying days supply at a time.
10pm comes round and you realise you have 3 cigs left.
At first you are an optimist."Two more tonight , one for the morning , perfect!"
Before you know it ,Its now 12.20am and you are down to your morning cig...
Then I tried to replace cigs with cigars.
Great I now have a $100 a day cigar habit to go with cigarette smoking.
