I'm 22 years old. I've been smoking for 6 months. When I started smoking, I used to smoke 10 cigarettes in a day. 1 month ago I started smoking 2 cigarettes a day. 2 weeks ago I was having liquor on a friend's birthday (I drink occasionally) after that we had vaang with malai kulfi. First 1 hour I was ok but then when I got back home, I started feeling suffocated and also started vomiting, feeling weak, legs started shaking, chest pain etc. I took pankreoflat after that and PAN40 and everything came back to normal. Next day I was alright and had home made breakfast, lunch, dinner and didn't smoke. 2 days later I had pizza and I felt uneasy. It felt like something stuck inside my chest. I was shocked but it got stopped after few hours of rest. From then on I started taking home made food and take green tea twice in a day and drink lots of water. But sometimes I feel like the food is not going down , it gets stuck somewhere in chest. I also feel chest pain in the morning. Is this digestion problem or lungs problem and what should I do now?
