Previously Gastric query enquiry.

Can I take pantocid 40mg 2.bd before meal instead PANTOP DSR. Because Chemist store told dsr is used for vomiting or belching but I have only too much due to that my food not digest. Doctor treat it's I.b.s but it's not. And my second query is can I take digene syrup 20 ml 2 times instead of gaviscon because both are Anta acid and gaviscon and PANTOCID 40 MG is currently keep at my home . and gaviscon will have to purchase. My currently medicine is equirex,goldcal,prothiaden 25mg2b.D,nexnuron,petril MD 0.5mg .and after meal PANTOCID 40 mg2.bd. But I don't have sleep problem sometime at sleep time and some time at night arround my abdomen tight arround 2am and after taking 2gas tablet I relief something then sleep comes that's happening to me 1 year after recovery of Bell's paralyse.
