Hi all. Iv recently given up smoking fags and cannabis. The habit lasted about 7 years. Both fags and cannabis. Other the last few weeks iv felt like I have mucus stuck in my throat that I cant cough up. I feel like it moves when I cough but it is constantly tickling my throat. Also when I cough quite hard I get really light headed and sometimes feel the need to pass out. Also when you quite smoking I thought you were ment to gain weight and I feel like im loosing weight.i have a doctors appointment today but was wondering if anyone on here could help also
