Coughing Vomit Breathless & throt iching

I consumed vodka 3 months back. I got lose motion nxt day. After 15 day again lose motion. Again after 1 month stomach ache. Now, I am suffering from cough since a month and it started when I took Pudin hara one month ago as I was having stomach ache. After taking pudin hara, I started burping due to its intake. After few hours due to continuous mint burps I started coughing. My stomach ache got cured in 3 days after proper medication from doctor but my coughing issue is still not getting cured. I have consulted many doctors and took several medicines recommended by them, but no relief. I feel an itching sensation in my throat and suddenly it start coughing and then vomit. But no heartburn feeling. During night time, in sleep I feel dryness in my throat and when I wake up to drink water it starts coughing and it’s too severe that I can’t even able to breath smetimes. Main problem left is coughing and then vomiting and iching. Please suggest medication. Already visited various Dr 1 by 1
