Hi and welcome to HCM.
It sounds lke lung disorder and the first thing to think about is chronic bronchitis
caused by smoking
. You simply must quit it and take certain medicines and inhalations. YOu have also high risk of heart disease
and coffee isnt helping in this.. I suggest to do ecg, chest xray and ventilation functions. Of course the most important treatment is changing dieatrry and life habbits. You are young and you shouldnt have such symptoms. YOu simply must evaluate this condition. Wish you good health.
