For a newbie I think 6 hits might have been too much... Especially if you didnt space it out... I've been smoking for 7 or 8 months now and 2 hits still gets me high... So for someone who never smoked to take 6 hits (especially if it was potent) is just too much IMO.

Next time, take 2 hits and wait 10 - 15 minute before your next hit... I can almost promise you wont get sick.
