Cooking fish symptoms and conditions

I was given omeprazole (20mg twice a day) for suspected stomach ulcers - though I was not experiencing current symptoms. Initially my stomach felt calmer but I felt very tired. Over the next few days I got more tired, weak and depressed. I completely lost my appetite and food tasted all wrong, also my sense of smell went off (e.g I accused my son of cooking fish but it was bacon). The only food I fancied during taking the drug was pineapple. I did not like the sunlight and curled up in a darkened room for 3 days. Had very strange vivd dreams. Finally checked the side effects on the leaflet supplied and decided to stop taking it. The tiredness and depression stopped straight away and my appetite returned, but also that evening very bad indigestion and burning which I had not had before taking it. Maybe this is because the stomach is over reacting to acid suppression. I am going to try natural remedies and cut out tea coffee and smoking if possible. Still fancying pineapple! Strange that though it's acidic itself, it seems to soothe the burning. Also fancying yogurt, greens, licorice, bananas and honey (not all together!) which I notice from other sites may be beneficial. Taking milk thistle to clear the drug out of my liver. Any feedback from people who have tried alternatives to this horrible drug?
