Man, I think you are not getting quite a big enough hit. If you are able to get up and go lay down, you are not gettin there brutha. When I fill my bowl and take a big hit (of yellow spice) It is very easy to take in a thickass oily hit, and I do not vape it like some do in a glass pipe, but I got a nice round bowl that I put on a small waterbong, and I put a half a bowl of my pot leaf or some good buds if there is some, and I put like 5 1/4 inch knife hits on top, and then roast the fuck out of it in one big hit. It's important to move the flame over the entire thing and just inhale really slow. If you practice Chi gung then you are familiar with the yogic breath. Let ALL of the air out of your lungs, and do a long slow inhale roasting the flame over the crystal and then roasting the weed as it burns underneath of it. You will wake up twenty mintues later with your head blown off by the experience.
There is no getting up, I let the smoke out and I go "BLIP" into another realm. I come back 20-25 minutes later. I've only done this a couple of times, and there is absolutely no discomfort other than the initial not confusion of not knowing where you are at. the yellow spice I get is very smooth to smoke and a huge single hit is definitely doable even with my hashed lungs from abusing marijuana for the last thirty yrs
When I do a half hit and leave myself here in this world but tripping on fractals and patterns and colors, it is a very uncomfortable experience for me. The electrical hum is disconcerting, and the tan and orange patterns can be cool, but it makes me tense and uncomfortable, even after doing it quite a few times in one day a while back when I had some. Damn wish I had some more of dat stuff, it is calling to me.
Peace ya'll
