if you shoot it, you get a 10x better high and you filter otu most of the cut. not only is it better, but it is like nothing youve ebver experienced. after a coulpe seconds, you can taste it in your mouth (weird since it never touched your mouth) then you ears start buzzing then you go into a dreamlike state for a few minutes, then wake up all jittery. its the best high ive experienced, just be careful, you can OD easilythis way. do a few smal test shots to find your tolerance
I, personally, recommend against this, though know a few people that do really enjoy it. Not I and the only person that's putting a needle in me is a nurse or doctor or lab tech that is doing so in the line of work, not for... "enjoyment"... well, maybe in a sexual context, but still not the same type of needle... that's a discussion for a different thread, and perhaps forum too though.
I've been up for 23hrs and 50min as of right now(typing this) and was tooting for about 14 of those hours thanks to an epic early birthday present.. no, not continuously, but a few lines an hour or two(which is exactly why I'm up typing on this thread right now at 5:40am lol. 'bout time to make coffee I think). And after about the 5th set of 2 small lines per side, I started getting sinus pressure and clogged up, as you say. I took an allergy med(4hr one, not sure which) and it helped, until I did more than the two small per side, but definitely helped, but didn't take another allergy med cause it had only been like an hour or hour and a half. So now I'm using saline mist and it helped just before and after a toot. Granted, this is the first time in a VERY long time I've gotten the chance to have some blow, especially enough to party like I did, so my experience maybe based on simply a foreign substance that isn't usually there, or any substance up my nose for that matter, and the high ass pollen.. shame we can't catch a buzz on pollen, I'd be set here!!
Anyhow, another option is guaifenesin, or mucinex(it's the active ingredient), but you'll need to hydrate with water, both your body and your nose, as it will dry you out..not just your sinuses and/or mouth/throat, but if not hydrated enough with water, not soda or something else sugary(I recommend Fiji water, pricey, but worth it), you can become constipated.. which can really suck, and hurt depending on how "dried out" you are.. Just thought I'd throw my two cents in on the subject since I found this wonderful site this morning.
Regards all!
