Gastro

I have been sick and in bed for 3 months now. First I had the flu then I had an ear infection.  Went to my doctor again I have awful pain in my stomach  no appetite and feel very sick and my head feels sick and sleep I toss and turn and watch the clock all night, doctors said I could have Gastro she give me opeprazole I have to take twice a day for 4 weeks and then one a day after that. Still don't feel any better have go see the doctor tomorrow. Does this ever go away I do suffer from IBS
