was gradual thing but obvious he stopped having obvious pain. Over time thought (we started at 5 weeks) it got to be a huge fight to get Losec into him so i cut down to once a day and after a few weeks stopped all together and is fine now, stopped at about 4 and 1/2 months. He still chucks but is now a happy chucker.
Good luck, its distressing to see them in pain and not able to help them, Hugs
