Hey Doc...
i am a 29 yr old male..i work in th hospitality industry

I dont usually get my meal breaks on time anf at time dont get one too...
tonight i woke up at around 4 and was feeling too uneasy, also I was finding it really hard to breathe
witout any hesitation i walked to the security office and reposted it to them..at once they called the doctor in the resort and he attended me.

having asked me a few questions and checking me,he concluded with me having gastritis and gave me some medical advice..

i wanted to know how can i get over this disorder and is it a real serious illnes!!
