Hi there!
You could try raising the head end of the bed or using multiple pillows to do the same and see it seems to help. I would also be suggest avoiding taking food atleast 2-3 hours before going to sleep. While antacids can be used for symptomatic relief, if the symptoms are severe and not relieved by medications, I would suggest consulting a gastroenterologist for additional medications that may be helpful. Surgical measures are exclusively reserved for severe cases that fail to respond to conservative measures.
Hope this is helpful.
Take care!
