Anyone diagnose me before I go to the hospital?

Alright well it's been a week now, I'm officially worried. Here's the story. Last friday I went out and really tied one on. No biggie, we've all done it, right? Well the next day I naturally feel like complete [censored] and spend the day in bed. Next day, I no longer feel hungover, but I can't shake this dizziness that I get whenever I stand up / sit down etc. This has continued SINCE SATURDAY. I dunno wtf the deal is, but it occasionally causes me to vomit and never goes away. Today I bent down to put my shoes on and was literally brought to the floor. I promised my mom I'd see a doctor (I only have major medical) if this continued for a week. I was hesitant to do this as it will surely be expensive, but I'm almost looking forward to it now. It is seriously impairing my quality of life (I can barely play cards, always feel sick). I have no symptoms of a cold or flu, but have been getting allergies this season when it's super hot out. Oh that reminds me, I wake up every day covered in sweat and sometimes get hot flashes like right now. Help me please.
