HELP.... weird feeling after smoking weed

Hey there i have come across a problem i hope some of you can help me with
 
I have been smoking regularly for 4 years now. 1 joint before bed 4-5 days a week and i have never had any bad experiences with it. Of course sometimes i have felt a little dizzy while being in bed after smoking a little bit too much but nothing major. I guess we all been there at some point.
 
Then about 4 weeks ago i had an incident. It was a saturday night and everything was normal i was going to hit the city with my friend and while waiting on him to pick me up i decided to smoke a joint, you know to jumpstart the party. i smoke half a joint and my friend arrived. i got in his car feeling a little high and everything was still normal. Then after 10 minutes it started to spin around in my head. at first it was a light dizzyness but quickly turned into a nightmare. I felt like the car was turning upside down and that i couldnt breath properly and i got a feeling of panic so bad that i just opened the door in middle the road and jumped out of the car. (and no i dont suffer from motion sickness and i never have)
 
while outside the feeling went away and i was feeling somewhat normal again. i decided to walk to the bar where my friend was now waiting for me. i went inside and after about 1 minute being inside the bar the feeling came back. The sound of the music and the presence of all the people around me just freaked me out so i had to leave. i decided to call it a night and walk home. Again while being outside and walking i was feeling somewhat okay. i made it to the train station and jumped on the train and sat down. once the train started to move the feeling came back. again i felt a feeling of panic and i just wanted to jump off the train. The rest of the trainride was torture but I managed to get home and amazingly i felt asleep
 
Next morning i got up and was feeling good until 2 hours later the dizzyness came back i went outside for a walk and the feeling went away and didnt return for the rest of the day.
 
The next day i decided to smoke a joint like i always do. Again i smoked half of the joint and the same feeling came back. i got insanely dizzy and nausea to the extent that i couldnt stay home. i had to leave my house and just walked around outside for around 3-4 hours before the feeling went away.
 
After those 2 incidents i decided to take a break away from joints. I didnt smoke for 2 weeks and throughout those 2 weeks i didnt have that dizzy feeling. I was thinking that maybe it was over and i tried to smoke a joint again. I got lightheaded and a bit dizzy and a bit nausea but it was nothing compared to the 2 earlier experiences, but still it wasnt comfortable. and every since that everytime i smoke a joint i get this feeling of being uncomfortable. 
 
The symptoms varie. but almost everytime i feel a bit dizzy lightheaded and nausea
[SIZE=11pt]but other symptoms are burp attacks, weak feeling in the legs, pain in my eyes and headaches.[/SIZE]
[SIZE=11pt]and it seems that everytime im sitting or laying still the symptoms come but while moving around they go away.[/SIZE]
 
Does anyone else have experienced something like this and does anyone know what this could be and, maybe even better, have a solution to it?
 
I love smoking weed. It feels like its a part of me. Theres nothing better to me than getting home after a long day put on some good music and light a joint before bed. It really makes me sad that i cant enjoy joints the way i did and im afraid that this is maybe a natural sign for me to stop smoking and i really dont want that to happen.
 
So please somebody give me some advice or solution or anything. Im getting really desperate.
