Did you cut down your usage before you moved?
If you are smoking heavily, and quit on a days notice, then you will go through withdrawals. I'm talking actual withdrawals, not just the sleep bullshit.
Cold sweats, anxiety, erratic mood, "fiending"
I,ve been a fairly heavy smoker for 12 years and had to quit two months ago due to trying to find a job. I did not experience any of those symptoms asside from still wanting to burn one. It was actually a lot easier than I thought it would be. Not one noticeable physical withdrawl. Maybe it just varies from person to person though.
