Glad to hear you're generally doing well, but sorry about the symptoms you're having. You're not having diarrhea, are you? What you're describing could be a side effect of dumping syndrome--common recovery symptom after stomach surgery.
Check out this link and see if it makes sense...

Good luck!

Sounds like you were very wise to visit the OR. Glad to hear you've been hydrated again and are feeling better. Keep sipping that water!
Very best wishes,
Sorry to hear you're still having trouble. If you're not already on anti-nausea meds, please request them ASAP...you won't want to hurt your wrap with those dry heaves. Hope you get things straightened around soon.
