Right so, I am on month 6 now - But I thought I would share my experiences with the new quitters, as personally I was a little bit of a hypochondriac after I quit - Especially since, for 90% of my life (I am 29 years old) I have had no medical problems at all, and on average get the sniffles maybe twice a year! So, this is my experience of quitting.
So after the first week or so, I kept getting very slight head aches and neck aches. They were not anything to go to the doctors for, as they were just little niggly pains, so nothing major. This still sort of happens every so often. As the weeks go on, I started to notice a general feeling of being a bit ''un well'' but nothing to seek medical advice about. I also started to cough up some questionable looking flemmy type stuff. They say you cough up black tar after you quit, so I guess this was it. It wasn't black though and there wasn't a lot of it, more brown in colour really.
Now the only good thing here is that although i felt un well or ''icky'' most of the time, I still felt healthier, in a weird way - so we need to keep this in mind.
After 2 months or so, i started to get bad dizzy spells, maybe twice a week, so not often. They would last around 40 seconds, then I'd feel a bit sicky for 20 minutes, and then I would be fine. In the early weeks, a runny nose for me was pretty common too.
I would also get a very fuzzy and foggy head. Sort of like I couldn't focus on anything...
So, even after 5 months, sometimes I still feel a little odd. Point is, you're going to get lots of things happen to you that seem odd and out of the ordinary, but this is only because your brain and body are used to functioning with all the chemicals laced in the ciggies, and once you take those chemicals away, your body then has to adjust to function without them. It's similar to how alcoholics need alcohol to just ''function'' - It's because the body is so used to it, it's not an alien substance anymore so the body thinks your removing something it needs to work. So this is why your brain and body just goes bat **** crazy on you because of all the stuff you taken away from it.
I am sure everyone is different with their symptoms and length of symptoms though.
