I last had a cigarette over a week ago. The cravings haven't been too much of a problem apart from when I met a friend for a few drinks on Monday night, I didn't succumb though. Ever since Tuesday morning's hangover though, I have been feeling depressed and unsure of myself. My performance and concentration at work (relatively new job, yet to prove myself) has been noticeably poor.
Has anyone got any tips for getting over these psychological withdrawal symptoms?
