Hi i quit smoking about a month ago, i was smoking 10 a day for 2 years. I have been mostly smoke free apart from the 1 or 2 during night time. at the same time i quit i started having severe digestion problems/bloating. Two weeks ago I had an endoscopy, colonoscopy, blood test, ultrasound etc. Everything came out fine. I am still suffering severly form bloating and indigestion, no matter what i eat. day before yesterday i started getting slight fever and dizziness. what is happening? is this just nicotine withdrawl? or do i need to see another doctor?
