Hi everyone, I am Tom, 25, and I've been quit for about a week after over 10 years. I quit cold turkey and have no desire to smoke, for some reason I have had no cravings either, but I'm just going with it. Anyway, for the past four days I have felt depressed, tired, sleepy and sick. Also have the strangest feeling as if I'm half outside of my body, I can't think or concentrate and it's pretty awful. Is this normal and has anyone else experienced it? Hope this doesn't last long. PS, I've also started looking terrible.
