I stopped smoking last Monday (almost a week) The first couple of days I felt fine. I have the nicorette 2g lozenges pack of 20 and I still have a few left. Some days I didn't need any, other days I've had maybe about 4 over the course of about 6 hours.
In the past 3 days I have been feeling incredibly nauseous, to the point I have almost been sick a couple of times as well as feeling absolutely exhausted. Is this normal? I have an appointment at the pharmacy tomorrow, but right now I just feel really unwell 
I have read up about smokers cold/flu, but I couldn't see anything about actually being sick?
