I'm kinda worried

[boywonder]

One night maybe a month ago, there was about 10 of us who stayed round a mates house, while her dad was in france. Anyway smoked and hotboxed her room all through the night, it was GReat fun. Probably my best experiance on cannabis.

The problem is, since then, nearly everytime i stand up, i get a massive headrush, and blackout. My vision comes back after like 10 seconds, and i dont collapse or anything, but i basically go blind. Its getting slowly better, but i wish i cud understand why it happens, its a pretty major thing, i mean if im with my parents and im just standing there blank for 15 seconds, theyll wonder what the fuck is wrong with me, anyone know what the cause of this is? besides smoking too much weed in one night

probs not eough sugar or food in your system or sitting down for ages gettin stoned then havenin to move will give u a killa hedrush, happend to me be4 when i was at a dealers hit some bongs and my m8s was like where going now i could harldy stand without leanin onto somthing got outside my visiion was all black and red with the colour draining out of it then i couldnt see had to sit down for a while when i finally did get up i was still well stoned and went on to have a wicked night

i dunno i might be crazy but i think headrushes r cool

straight up dude. and then you can kind of collapse and lay there and it's totally cool feelings

I herd that when that happenes you haven't had enough to eat.. like you need to eat MORE!! but IDK =S that's just what I heard

yeah i used to get them, but not this frequently, it was after the night i smoked an excess amount of dope then it happend to me every single time i stood up, and a ridiculous amount, i mean total vision lost from standing up?!

i get that when i take elevator tokes (take a hit and stand up realllly fast)
