Can't say I've ever experienced those symptoms either. The only withdrawl I ever have is thinking "damn, it would be nice to have some right now". Especially when I have a headache, nauseated or just need to relax after working all day to sooth my aches and pains. Other then that, I find I function just like I did before I smoked. Lately I've really been off and on with smoking. So now when I don't have any, I don't even really think about it. I just do my thing and smoke when I get the chance.
