Shit I never knew that, and I feel all of those things right now. I wanna go kick someones arse, I just dont know who?
I know nobody asked for my advice in this thread but I'm gonna give it anyways

I smoked for about ten years... I was up to smoking two packs a day. One pack was a good day for me. I just don't want to come off like one of those condecending assholes who when they quit smoking go on some crusade and feel the need to tell everyone about the evils of smoking and how they stopped. All they did was piss me off and make me want to smoke more. So I hope I don't sound like that haha.
But I promise you Islame and anyone else quitting that these symptoms will be totally gone in two weeks.
And also you will never quit smoking unless you actually want to quit. and actually "wanting to quit" is different from just "knowing you have to quit".
