Hi alz, I know what you are going through. We made the decision not to medicate as he wasn't at all distressed by the throwing up even though it was frequent and large amounts. We just elevated his head nearly all the time, and put him up on my shoulder for 30 mins after each feed. He's now 5 months old and still vomits very frequently (like every 10 mins if he's on his tummy) but he's a very happy little boy. He isn't big, and we did have some issues with his weight gain early on, but I received some very good advice just to throw food/boobies at him as often as possible to try to get more in - he always returned any excess. It's not much fun when you're being vomited on constantly, it gets me down some days just being covered in vomit and not being able to wear nice clothes or even sit with my son on our couch, but I'm just so happy he's healthy and enjoys life. Hope things settle for you, ours got better at around 6 wks.
