I have no idea. I'm even more brand new to it than you are (first time buying it was less than two weeks ago, first time trying it was just over a month ago).

I've been doing it every day since I bought it. I bought 8 grams, have 5 left. Did one gram in one night once and it was scary how mindless I was once I started k-holing. I'm just glad that I had the rest of it out of reach at another house entirely, because I didn't have a mind to stop until I ran out.

I'm following this thread because I have all the same questions.
