Yep got really sick and couldn't breathe. It was nearly impossible to smoke. My Dr. suggested I try and quit. I didn't want to but it was sort of natural because I felt too bad to smoke so I just sort of laid them down. Now I'm on day 5. I have had some cravings so I chew tobacco which is sort of gross but gets rid of the nicotine craving. I don't do it much, a couple times a day and I don't see myself continuing it too long. I have had a little anxiety, irritability but not too bad. Overall I'm very proud of myself for being smoke free!
