I found this forum yesterday after a google search for "Quit dipping brain fog" after a visit to a neurologist. I started my quit on January 13th of this year. I kind of cheated as I decided to use Chantix to take the edge off and the Chantix did help. The first four weeks were not easy, but very manageable. So with things going so well, I decided to quit taking the Chantix cold turkey. 3 days later(Feb. 11), I had extreme brain fog set in. Over the course of the next 2 weeks, I had anxiety and 2 bad episodes of de-realization. I freaked out, started taking Chantix again and went to a doctor. Since then I have had blood work, brain MRI, sleep study, visit with ENT and on this past Monday, a neurologist(Docs have not found anything abnormal yet). The neurologist did say it was probably my body trying to find a new equilibrium after quitting. This brain fog has freaked me out, I never tied it to my quitting nicotine because the 2 times I tried quitting before(both times around 6 months) I did not experience anything like this and that the brain fog did not set in until week 4. After finding this site, I feel encouraged that it is just my body trying to adjust to a nic free life.
Has anyone else had it last this long(I'm on day 62)? I still have it 24 hours a day and it does not seem to be letting up?
Thanks in advance for your help.
