well..just an update. 9 wks and still smoke free. don't seem to have any extra endurance or energy like i thought i might feel. food taste the same....still eat about the same amount...sleeping patterns havn't changed...really only a short time into this new lifestyle, so time will tell....what i do notice is my sense of smell. i can now tell if i am standing next to a smoker. you sure can smell it on people, especially when they come inside from just smokeing. a strong odor i never realized was so intense......no wonder i couldn't get a date!! lol
