The first and foremost thing to do now is to quit smoking for good, as all others have suggested here. Most of us have gone through all the side effects of treatment you are experiencing now and if we can overcome them eventually, I believe you won't be an exception. The process is painful and you need very positive attitude and strong will power to cope with it. I also came to a point that my mouth was so sore that I couldn't take any pills orally. My doctor prescribed the pain killers in syrup form and a kind of liquid medicine that helped me numb my mouth before taking my meals. As for the nasty taste buds, you need to be patient and keep on reminding yourself that you need to eat for life now and it is too luxurious to think of enjoying the food at this moment. Hang in there and the light at the other end of the tunnel will soon appear.
