Oh gosh, so sorry to hear you are having a rough time.

My daughter who had the baby in March....little Matthew has the same problem, acid reflux, and she even quit breast feeding (which was fine with Juli, she said she felt free) but at 4 months, he is still having an issue. We babysat the kids one evening a couple of weeks ago, and for the first time we really saw it, Matthew cried from just after 8pm until the 10pm feeding and nothing we did helped much - we just took turns walking and rocking him - he definitely likes the walking better, as you said Masaki, I think the gravity helps the discomfort - thank heaven Kate was already in bed and asleep, it was a very long two hours.
Good luck - I'm sure things will get better soon. Keep the faith Amanda, it all works out eventually. :hug:
