My husband was sleeved a little over 8 weeks ago. He did fine for the first 3 weeks. After that he became unable to keep anything down. Even a simple sip of water makes him vomit. He has stomach pain, a chronic cough, burning in the throat, mouth constantly waters, extreme fatigue, & burping. He is currently in the hospital for the THIRD time for severe dehydration. We are losing hope & not getting many answers. Also he has been taking Zofran for nausea & Prevacid for acid relux. Any advice?? We are desperate!
