I've been trying to give up smoking for some time now, with varying degrees of success. Whenever I've managed to go for longer than 2 weeks, I have the same 2 side effects, which on paper should be mutually exclusive. I have terrible insomnia, which somehow is punctuated by short bursts of sleep, which are in turn punctuated by nightmares. No your typical nightmares either, more psychological nightmares where the threat of danger feels much worse than actually being in danger. Worse thing is you don't wake up (cos you were never sleeping) Anyone experienced this? Any advice?
