PAWS usually only last about 90days to 120days in my experience but you can have the symptoms up to one year at the outset that is anxiety, irretabiltiy, mood swings, problems sleeping, depression, etc.

After three years if you are experiencing these symptoms, there has to be some underlying issues that have to be addressed.

Please go to see a therapist, addiction expert or a doctor who is certified in psychiatry and addiction - someone that you can discuss what you are feeling and work on the reasons why. Also you may need some medication to help you feel more comfortable. Hope this was of help.
