dude that dont happen all the time. Ihave had that happen to me, almost everything you said. I either lay down and pass out or just try and walk it off outside. One time i almost couldnt stand for like 5 mins, like i was piss drunk. That hs only happend i think 3-4 times. The teeth chittering thing happens alot, i think its normal. I think weed will sometimes make your muscles spas cause sometimes i shake and others im still as rock.

How long did all of this last? It lasted me abou 10-15 mins.
