this is not an idiotic question by any means.
it all depends on the quality, but starting off with .05 grams isn't such a bad idea. if you do .1 grams and it's pretty good shit that will be plenty, but i would start kinda low to get a feel for quality. or you could blast a line and anywhere .05 and .1 g's should be plenty to give you the rush. i like to do just enough to get the rush, and then continue with that, .25 grams is a lot to IV. you should wati anywhere between 15-30 minutes to do another, depending on you're willpower. don't try and push it.
i guess you probably already know this, but the comedown is a bitch and it doesn't last very long. the russh though, aahhh the rush.
peace, outkast
