just 3 days? and desire to smoke will disappear? I think I'm too weak person to give it up so easily. Think it can be difficult for me
The desire to smoke will last six months (100% clear in two years) but the first three days are the most difficult. It depends on how much you smoke of course. I was on 20 a day. You will need to see if you can find motivation. For me I found I was having trouble breathing, early emphysema, this gave my subconscious enough of a scare to help me stop. Most addictive things are easier with a little deep fear driving the desire to quit. Emphysema also causes mental confusion, lack of alertness, bad for trading.
Coffee is however perfectly ok. Don't have a relationship with someone who disapproves of coffee, there is something wrong with them
