I've been quit for 67 days and I am still going strong, but insomnia and anxiety have become increasingly acute issues since about week 4. My sleep is fragmented, where I wake up within an hour of going to sleep. I'll usually wake up 2 or 3 more times at night. Sometimes lying flat bothers me and I move to a recliner to elevate my head. Acute anxiety often translates to a shortness of breath (probably panic and hyperventilation). I believe I'm largely past physical symptoms and I've been checked out physically by my doctor with no issues. Has anyone else dealt with these types of issues in later stages of their quit effort? Quit literature often stresses the first 3 weeks, but my issues seem to be in the following months.
