First off, I prefer to refer to this wonderful plant as Salvadore Dali, due to it's mind warping properties.
I have used 40x many times, and for whatever reason, I just draw a blank when it comes on full force.

My first experience was amazing. I was at a local nature reserve, sitting on a bench near the parking area, alone in the dark. I packed as much as I figured I could consume in one large pull, and used the torch lighter to fire it up. After holding it in as long as I could, I exhaled, and immediately felt a strange pulsing sensation in my thighs. I opened my eyes to see what I can only describe as thirty foot tall rainbow turnips extending from my legs, with the rainbow colors swirling like an old school barber shop pole. I then heard the people in the parking lot whispering about me. "Did you hear about (my real name, with a grade school Y at the end of it)? He smoked that Salvia stuff and never came back..."

I giggled about that, knowing it would only be a short ride, and that Ive had plenty of intense trips before. My surroundings became layered with multicolored, concentric circles of rapidly changing numbers and symbols, and the trees that I could barely make out through the kaleidescope I was seeing appeared to shake violently, although there was no wind to speak of.

After that, I have no recollection at all. This has been my usual experience with Salvadore. I remember things getting intense quickly, and then draw a complete blank. The only times I can remember the whole experience was when I used extemely small doses. I would like to note that I have never had the experience of becoming something else, as alot of people do.

So, I guess I'm wondering if anyone else has this experience frequently. I wish I could remember, since alot of the things that other people describe have an eerie familiarity to them, and I think I've been to similar places, but can't be sure.

My advice to you would be to try a lower extract.
40x is a lot!

Maybe try 5x or even plain leaf.

You'd be surprised how far plain leaf can take you when done the right way.

Considering that Salvinorin A is the most potent naturally occurring hallucinogen known, “packing as much as you can consume” is quite irresponsible.

Have you considered weighing your doses? If not, why not?

A moderately strong dose of legitimate 40X is about 10mg. I don’t have exceptional lung capacity, but could probably easily inhale five times that amount in one inhalation.

Yes, I've considered it recently, and I thank you for the info on dosage. I guess I just went a bit overboard with it, since I'd had straight leaf prior to the 40x and it didn't seem to have much effect at all on me.
