Ok I know there are symptoms you go through...but I have looked everywhere for answers to these two questions...it is normal for your mouth to be super sensitive...like you have burnt your tongue on hot chocolate and I have what feels like a lump in my throat...comes and goes but if I hold my throat it feel like it is closing off... and just generally feels like a hair ball or caught pill in my throat. Is this normal? Is this related to my kicking the habit, or could this be something else? I am a little worried.
