The nicotine would explain it. You're taking 80mg of short acting nicotine all day and then you go to sleep and within a few hours your blood nicotine levels drop to nothing. The brain doesn't like that. For reference, the highest dose nicotine patch is 21mg and that releases over 24 hrs and this provides enough nicotine to calm the cravings of even the most hardcore smokers.
But also you don't appear to be understanding what your doctor is telling you, and that is a problem. It can happen when seeing a specialist or if there is cultural difference. Get a copy of your medical record, it'll show his notes and in explainable format so anyone (insurance, other docs and nurses, lawyers, etc) can understand it. By law they have to give it to you when asking and it's a common request. And it's protected information so only you can request it. My guess is there's probably something going on with you that he just didn't explain very well.
