Hallucinogenic doses

[SinCitySpanky]

I've been experimenting with different hallucinogenic doses(Acid, LSD, and Trip to be exact) the past few days. The thing is, the effects havent been all that strong. Of the three, Acid was by far the most powerful. Yet, I still found myself wanting something much, much stronger. Also, I havent had any hallucinations what-so-ever.
So what are some of the much stronger doses out there? I'm willing to try just about anything.

Thank you for the help,

It's next to impossible to get open-eye-visuals with I-Doser. Closed-eye-visuals are almost rare, but not impossible.

Well, if the room is pitch-dark then it doesn't matter wether your eyes are open or closed (during hallucinations, cause in the beginning blinking may distract you).
