are common in nicotine withdrawal
and would be relieved by nicotine gum. But the nausea and vomiting
after using nicotine gum in the morning is because more nicotine is suddenly released into your body than your body is used to. Try using a nicotine gum of lesser strength or for a lesser time. The best option would be to consider quitting tobacco altogether.
If you are taking beer regularly in excessive amounts, that too can be associated with these kind of symptoms. Night sweats are seen in alcohol withdrawal
Hope this has been of help. Best wishes.
