K-Holes, for me, are not scary AT ALL. A K-Hole is like being wrapped in a warm blanket by your mother if LSD is insanity, ya dig? For me, it induces more positive feelings than Opiates (actually, no, but it's on par). It's nothing to fear, just something you want to ease into. Don't K-Hole your first time with K, you probably won't like it. But if you work your way up, and when you finally decide you wanna K-Hole, take the K in spaced out bumps so the Hole comes on slowly. 50mg every 5-10 minutes will suffice. Continue until you feel well fucked, 150-200mg will be good for a K-Hole.
When you get there, it should welcome you and lead you. Don't even TRY to experience anything when K-Holing for the first time, relax, try to become meditative (very easy on K) and just let the Hole and the music you are listening to carry you. It should feel natural enough if you have been experimenting in lower doses. First timers would be blown away by it, won't know what to do with it and try to fight it. Ever tried to fight an Anesthetic? Lol, it's not fightable, and you will lose, so embrace it and relax and it will be positive.
