Your success at getting off the acid reducing drugs will depend on if the original cause of the problem has gone away or not.
For example, if your original problem was due to things like a high fat diet, smoking, stress, being over weight, etc., and you have fixed those things, then you can probably be successful weaning yourself off the medication.
But if the original problem has not been fixed, such as if you have a defective LES valve, large hiatal hernia, etc., then your problems will likely come back when you wean off the medication.
So if you find your symptoms coming back once you have tried to wean off the medication, you should probably see a gastroenterologist to figure out what the root cause of the problem is. The medication just treats the symptoms and doesn't cure the root cause.
