Has this happened to anyone else? If so what did you do about it?

I'm 15 years old and sense I was about 6 or 7 I have sometimes waken up in the middle of the night dizzy. Now they are 3-8 months apart. But when they happen it is probably the worst experience of my life. I have fractured my growth plate in my elbow and dislocated both of my elbows and I wold honestly say I would rather have that happen then these "dizzy spells". Okay so after I'm no longer dizzy I always get sick to my stomach and well you know... I throw up, so I'm sick all day. Now I have gone to an ENT and an allergist about it. The ENT has done about 7 sets of tubes in my ears, taken out my adenoids, and thinned out skin in my noes in the hopes to stop them, but that never worked. The allergist has diagnosed me with asthma, so I have an inhaler, pulse a asthma pill, allergy shots, and an allergy pill, also all in hopes of stopping the "dizzy spells". But that hasn't helped ether. I have gotten an X-ray of my head before but nothing showed up. I want these to go away so bad. So if this has happened to you and you have gotten rid of them what did you do? Or if you deal with these what should I do. Or if you know someone that this has happened to what did they do? Please and thank you I'm desperate and would try any thing at this point.
