how long till this works!!

You'll know...

See my post...elsewhere. I don't know where, one of the more recent acid threads. The acid I did took FOREVER to work. Also, don't expect really intense visuals. A friend and I fucked with the color on his TV because the scrubs on Scrubs looked really really bright, like the color was turned way up. Twisty faces (see Fear and Loathing in Las Vegas when Raoul Duke first pulls up and the vallet takes his car - something like that).

Stare at the walls or carpet, or just close your eyes.

Look for patterns, on the road, in the trees, in the carpet, everywhere. I often see letters, pentagrams, etc. Closing eyes brings fourth mandalas, fractals, and other deeper more divine things depending on what you believe in. Look at the sky and hear all of the voices of all the prophets in all the tongues of the world. Look to the earth and speak to satan and mother nature.
