hi there. My friend is feeling dizzy,legs and arms feel heavy and lifeless. She feels nauseous and has a unsettled stomach , she has vomited once, an hour ago. She says she feels out of it and spaced. We are currently on vacation and have drinking heavily most nights,including last night. She has also been a bit stressed too. She is aware of her heartbeat more than usual too. Just wanted some advice please as we can t get to see a GP today, our only option is Accident and Emergency, and we re wondering if this is necessary. Many thanks.
