jack19962810 - yes lifestyle changed, one major change I did is I stopped drinking coffee which my doctor told me is the trigger. I ate tomatoes (part of my salad) the other day and parmesan cheese (also part of my salad) and I did not feel any shortness of breathing after that.
After 2 weeks taking omeprazol 20mg twice a day, I can say that my breathing really improved. I will maintain my daily exercise routine and diet but will consider to drink coffee again in the future.
