Just reading through some of the blogs and I noticed that some people are saying they are feeling tired .... I was like that and for the first three weeks I was an absolute couch potato. All I could focus on was silly computer games (anything that took my mind off cigerettes) . Don't worry about it, this will pass and hey if it stops you smoking that is all that matters. Give yourself some leeway, this is a huge thing that you, your mind and body are going through. I can honestly say it does get easier .... slowly does it. Don't let that awful nicotine win!!
