Well I ve been having acid indigestion problems as it seems, I usually get it once a month. I will get a pain in my stomach for about 1 night, and then when I wake up in the morning at a random time it will just get very very severe and it takes about a week for me to fully heal from it. I have been put on Omeprazole. I started taking this medication in April. I felt fine for a little over a month and then it came. I drink a lot of cokes and I feel sure that it s the problem. But at school I do not eat lunch and that morning I had a glass of coke and nothing else. The pain started that night and at about 9 in the morning it got very bad. It s been about a month now and I ve felt fine. I ve been drinking water and eating meals regularly, But im still afraid it might come back. I usually have 2 cokes a day maybe 3 but I drink PLENTY of water. I m just worried it might come back
