I switched to vaping.
The key there is getting a good vape kit, go into a vape shop and explain and try some vape juices out in the shop - they may taste funny but remember you still have a smokers tastebuds and so you aren't really getting the true flavours yet.
Concentrate on how you feel after a hit of vape, does it give you the same nicotine hit as a cig (it should, you should feel satisified).
Thats the bit you need really, the flavours and all the other faffery around vapes can come later.
Then just tell yourself 'ok I want a fag, but Ill vape now and if i REALLY want a fag afterwards I can have one...'
And do that every time and you will find if you got the right vape, that you NEVER 'really' want one afterwards.
After just a few days you will feel freer, you will lose the smoker smell, you will smell other smokers a MILE off and it'll probably give you a headache if you are shut in a small space with one, and things will start to taste better.
You may have a sore throat and a cough for a few days, thats normal, getting rid of the crap you built up from the fags.
Vaping gets you out of the habit of fags - you still get your nicotine but you will lose the habit of marking out each day in fags, how many fags is this dog walk, I'll do this and then have a fag, I'll just have a 1 fag break... oh no i can't go do that ive no fags...
You can sit and hold the vape and not actually vape it - think about how many times you light a cig ... and then actually arent really smoking much of it (I used to sit down to write an article or blog, light a cig.. then type away as it burned down! I think half the cigs I lit I didn't actually smoke!).
Then once you have htat habit cracked you can reduce the nicotine and bust the nicotine addiction, then you can dispense with the vape entirely if you want.
