It's usually from lack of oxygen to the brain, since ur forcing so much smoke into your lungs, and barely if any O2 is present. This can notably be made worse from getting up and going somewhere, the best solution when ur head feels lite is to get your breathing under control and u should start to feel better. I found this out the hard way, i took a huge hit froma bong, and damn was i gone. I got really light headed and started to get nervous, heart rate was insane, and i got up to get some water and i felt sitting still was torture. Needless to say that was a big mistake cause i started to black out and loose all motor skills. Next time just pop a seat and try and breath normal, the only thing that helps is getting oxygen back to ur brain. try closing ur eyes too, and take steady breaths, u may not enjoy it the first couple mins, but trust me its better then anything else at that point.
