I felt better when I quit smoking...for a week or two. But during that time, the withdrawal symptoms were creeping up on me to the point that I just couldn't stand the anxiety and insomnia that 1mg Klonopin (rx from doctor) wouldn't even relieve.
So I started smoking again, and switched the Klonopin to trazodone (rx from psychiatrist) at night, and it seems to be working better for the insomnia. I'm still smoking because I'm not quite sure I'm ready to try quitting again, despite a bout of severe acute bronchitis. I just need to have things under control. Hopefully, once I get my living room rearranged, I can exercise and maybe have my mental health under better control, so I can try quitting again.
But yeah, it does feel better to quit, for a few days. Good luck on the withdrawal. I hope you don't experience any symptoms that interfere with your life.
