Our 21 month old son has been vomiting once a day for about two weeks now. It is usually after lunch, when he is laying down for his nap, but not all of the time. His CF doctors don't know what is causing it. We have an appointment with his GI doc on Monday. I'm wondering if anyone here has any ideas...we would be very appreciative.<br><br>Here is a list of his daily meds:<br>Lansoprazole<br>Ursodiol<br>ABDEK vitamins<br>Vitamin D<br>Cyproheptadine<br>Miralax<br>Zenpep<br>Ventolin<br>Hypertonic Saline (3%)<br>Pulmozyme<br>DuoCal<br>Salt<br>Vest - 30 min, twice a day<br>Saline Nasal Spray<br><br>None of his meds are new. He did recently have a g-tube placed (beginning of April). We haven't had any issues with it. Last week, he did a barium swallow study, which showed no reflux and no blockages. They also said it went through his system quickly.<br><br>Any ideas or suggestions would be greatly appreciated! Thank you!<br><br>
