How do I get rid of acid on my stomach I have been burping and it smells like rotten eggs?

Reflux. In order to control reflux you will need to increase Omeprazole to twice a day befor breakfast and dinner and you may want to add Pepcid (famotidine) at bedtime. You should also wait at least 3 hours after dinner prior to going to bed. Also avoid citrus products and fried foods.
