I just found this web site and have just read through these posting.

I am glad I did because I asked alot of the same question when I was told my little boy had reflux at 4 weeks.

Like most people it started with the vomiting that was so bad that it shot out so fast it missed his bib and ended up on the floor. This happened at nearly every bottle so we were admitted to hospital to check he was losing any weight. We stayed in there for 2 nights but he seemed to be keeping some down as he still was gaining weight but only small amounts.
We were sent home with Losec, Zantac and a prescription formula as they thought he may have been lactose intolerent. Our dose for Losec was half a tablet once a day and the Zantac was only for a couple of days until the Losec kicked in. Once we came home the sceaming started ( this could last up to 4 hours especially around 4pm to 6pm) but the vomiting decreased, this went on for 6 weeks until he was 10 weeks olds. I ended up back at the doctors as my son is a twin and I wasn't coping with it and having to look after a second baby. The doctor increased his dose to half a tablet twice a day at 10 weeks (he was 4.5kgs) after about 4 days on the increased dose I had a different child, he actually smiled. The screaming stopped and the small amount of vomiting I could put up with, we just feed him smaller bottles more often.
At 12 weeks we swapped him back on to normal formula and he is fine. He does vomit a little more on the normal formula but it just flows out of his mouth, not shoting out like it was. My doctor has told me to try to go back to half a tablet once a day 6 weeks after we have him on solids and if he is okay give it a couple of weeks then cut it out too.

I also with the tablets stick half in a sringe and suck up 3mls of water them wait about 1 min until the tablet dissolves then I just give it to him like that. If he does have a vomit you can see small little black balls in it.

If your doctor is only saying to take half a tablet once a day and it isn't working I would try and see why you can't go up to half a tablet twice a day. I can't believe how much that extra half a tablet made a difference to my little boys life and mine too.
Last month he gained 2lb 8ozs not too bad for a reflux baby.
