Well, the easiest way is to relax and do this humbly and treat it with respect. That anxious feeling is hard to let just pass over, but just try to stay calm and focused and surrender. Try meditating for a little while before and state your intention to yourself and know that everything is going to be okay. Or just jump off the deep end and learn how to swim.

Just move the dose up gradually. You've done 15mgs and come back. Maybe do 15 again a couple of times. Then, if, and when, you feel ready move the dose up to 20mgs.... If you have good technique you won't have to go past 25-30 mgs to have a full hyperspace immersion. I can do it on 20mgs.

Peace.

BTW. Nothing can prepare you for it is true. However it is not nearly as fantastic as it sounds and it's more fantastic that you might believe.
Actually if you'v done 15mgs and experienced visuals you are pretty well prepared for what is to come with larger doses.

Just remember to stay present with yourself. Keep a dialog going in your head if you need to...it will ground you to the fact that you are still connected to a living body.

Peace

I found the best way to get over the virgin anxiety was to do small amounts, gradually increasing the dose each time. I felt like it prepared me more and more of what was to come without having to dive straight into the abyss.

Don't feel bad at all brother..everyone gets that pre-flight anxiety, even those who have done it hundreds of times can still get it. It's hard not to when you know that the self you think is yourself is about to get obliterated. This is why meditation is so important..look into that and yoga if you haven't, especially pranayama..deep and slow breathes are key. When used in conjunction with a low dose this work wonders at calming the mind/body and dissolving that anxiety

It helps to clarify your intentions for taking in the molecule and even something as simple as smiling once it is all inhaled can work wonders.

Getting your feet wet first helps..but, that said; every time i jump off the deep end into oblivion i always am extremely glad i did so afterwards ..so keep that in mind

(also, you might want to look into changa and caapi/rue)

SWIM appreciates the words of wisdom given to him and is taking everything that is said in mind.

If working your way up in dose seems to make sense, don't let me argue that.
For me though, there exists an obnoxious threshold right at the precipice of breaking through. it seems to be the place where all beings make fun of my attachments, haha. So if I get to that threshold, I would prefer to dive on in.

Heh. I hear that ! I've had fantastic, GREAT, as my circle and I call, journeys, but I pretty much always get quite nervous before that first pull.
I personally never really dosed up and up, I didn't meditate I just got into it. It was my first experience with psychedelics, and I dont do any other drugs or even really drink. Still - I jumped into the deep end and "they" were gentle with me. I'll say this it changed my thought process on what were about, even if I can never quite remember the jewels of enlightenment I am bestowed each time.
I think it's only fair to say I've had the darkest trips as well. Bad bad places I'd rather not ever venture again willingly, what felt like dark entities and other nasty vibes which lingered for a short time upon returning (30 mins of Vibe were talking about) - but I still have come out of these... Lessons with knowledge and thankfulness.

In any case you'll be fine, 5-15 mins of the most amazing experience your bound to ever discover and then it's back to reality!

Do it and let us know how you went !
