A Rough Week

Beau threw up last Tuesday evening right before bed. Then he threw up the next day, Wed, all day no matter what he ate. He has thrown up every day since. And this is not spit up, it is the projectile vomit. He hasn't had any formula this whole time cause it only makes him worse. He has always been on soy formula but it hasn't made any difference. We have been to the doctor twice during this last week and he is now on an antibiotic cause we didn't know what else to try. He has lost some weight. And his mommy is getting very upset and a little depressed. I don't know what to do. He isn't teething, and from what I have been told, he shouldn't throw up when he does. Tk and his dad gave him a blessing last night and he has held his juice down all night and so far this morning. I gave him 3 ounces of watered down soy formula and that hasn't come up yet either. But he usually eats 8 ounces in a sitting. Has anyone been through anything like this before? I hope he is getting better now, I know the blessing will help, but I have no idea what caused all this. It's been pretty frustrating. I feel so bad for him. He is always hungry cause the juice and gatorade is never really satisfying and it has been 7 days! I don't know what to do. It's been a pretty hard week. I have hope since he held down everthing since last night. And I definately have faith in blessings. Again, can anyone relate in any way? It would help to hear anything.
