If you can find a way to use your own free will and self-discipline to stop the bad condition then that seems preferable to using a drug. Maybe someone doesn't have the willpower in which case it's good that we have the drug.

With regards to omeprazole, I changed my diet a bit and no longer needed the omeprazole. I don't know exactly what it was, but if you can get off of a drug because you don't need it anymore that seems ideal.
