Last month I was smoking everyday, almost 3 times a day. Now Im just smoking once per week at most. Im feeling kinda "sad", like something bad is gonna happen. Like Im worried about something but I dont know why. I also feel kinda bored. Sometimes Im bad tempered or very irritated without a reason. My appettite is ok, I dont have problems to sleep. Also my short time memory is working better... So, are those withdrawal symptons?
