The most i've ever used in the course of a night is about 1/4-1/3 of a gram, and on that night i had at least 9 vodkas. Now i am someone who is seemingly immune to hangovers, but i got one that morning. Took 3 para's and i felt OK, not great, but ok. In fact it really wasn't that bad without the para's, which made little difference...
At some point i'm going to try just coke in a night, and go furthur than before, what would you recommend, 1/2? i'm certainly not getting through a gram in a night, that's for sure. I don't know how pure this stuff is but my dealer says comedowns are hardly an issue (for him)
BTW, do you tend to experience them after waking the next day or during the night as the drug wears off? Because i think this 15-30 minutes of effects is bullshit, i only had to upgrade every 1-2 hours on several occassions to still feel the effects, but i know the effects are similar in some respects to alcohol. I am inexperienced with it, luckily, i have valium, and will soon have xanax at ativan(presumaly roughly as good for comedowns?), but surely if you coke till late and wake up with a massive comedown, taking a downer is going to send you right back to bed...
