about since november i have been feeling very sick at night and the only thing that seems to make it feel better is if i burp alot, it is really upsetting me and i want it sorted. I have been to the doctors twice and their prescriptions have twice failed. At the moment i am stuck taking gaviscon tablets everynight - which are rather expensive after a while. I wonder if anyone has any suggestions to what it could be...my doctor said that some sort of flap thing wasnt keeping the acid in my stomach when i lay down, but i think they were wrong since it now happens when i am sitting up. please help me any ideas. i am currently doing exams and my family think its due to stress, i however feel different. any ideas at all...thanks
