Horrible bloating last night. vomiting emptied my stomach enough to sleep. even water feels like my schomache is just retaining all intakes. advice?

Stay hydrated: You must stay hydrated, and if vomiting is preventing this, you will have to go to the ER for intravenous fluids. Most likely cause is a stomach infection form a virus, or bacteria. Ok to wait a day or so, but if your urine is dark yellow, you are thirsty, and your skin seems stretchy, then just go. It could be very serious. Hope this helps!
